In doing so, this removes all uses of the Encoder's stream operator,
except for where it is currently still used in the generated IPC code.
So the stream operator currently discards any errors, which is the
existing behavior. A subsequent commit will propagate the errors.
Previously when there was no difference between the sum of the
max and min-widths of all columns of a table, it would result in a NaN
value being set as the column's width as there was a division by 0.
This would result in 2+ column tables being reduced to only 1 column.
Previously when resolving an attr or var-defined property
with a 'not-set' value like this `property: var(--ValueNotSet)`,
we left the property unchanged (as an unresolved) and
added it to the computed-style of the element.
We still don't change the property but rather we now also don't set
unresolved properties in the computed-style.
This is an intended behavior.
The specification suggests that, on resolving an attr or var property
(custom properties) we have an invalid property when neither the
variable inside the var, nor the backup value could be resolved.
An invalid property must be inherited or defaulted depending on it's
type. We already do this with every 'untouched'
(as in m_property_values contains no entry for it) value.
So not setting the property results in an inherited (or initial)
value by a later-called function.
This also fixes another problem, where
`text-decoration: var(--NotSet)`
wouldn't be inherited because the computed-style of the
parent element hasn't set `text-decoration` but rather
all it's long-versions like `text-decoration-line` and so on.

This regex is pessimistic, so there might be more files that don't

If text-top or text-bottom are given as values for the vertical-align
property, actually use them and calculate the respective position of
the element.
The actual calculations done (using the font_size, descent, etc.) are
not exactly how I imagined them when reading the spec, but the results
seem acceptable when compared to other browsers.
Both Element and DOMTokenList are GC-allocated objects so they can just
mark each other instead of using the old strong/weak pattern we use in
ref-counting ownership models.
The only difference between these two values is that `hidden` has
different behaviour for border conflict resolution for border-collapsed
tables in table layout, which we don't have yet.
This gets rid of the main border around the repository information on
the GitHub repository page.
Unlike client{X,Y} which is relative to the current viewport, these
offsets are relative to the left edge of the document (i.e they take
scroll offset into account).
Fixes the y-position of rows when indicated through the display
attribute `table-row`. Previously there was no y-offset between rows and
so they would overlap.
Required by Twitter to move the input caret of the 2FA <input> element
to the start. However, we don't currently handle individual <input>
element selections.
As per Fetch, we are supposed to store cookies from Set-Cookie as soon
as we receive response headers for any HTTP response, even in error
cases.
Required by Twitter to login, as it sets cookies via XHR.
Implement collapsing of a box margin-top and first in-flow
child margin-top by saving function that updates y position
of containing block inside BlockMarginState and then for
every child until "non-collapsed through" child is reached
y position of containing block is updated by calling
update_box_waiting_fox_final_y_position_callback.
Previously y position of boxes in block formatting context
was calculated by looking at y position of previous in-flow
sibling and adding collapsed margin of "collapse through"
boxes lying between box currently being laid out and it's
previous in-flow sibling.
Here introduced BlockMarginState structure that maintains
array of currently collapsible margins hence we no longer
need to look at previous sibling to calculate y position
of a box.
Fixes a bug where when you had spans that that were bigger than the
grid, would create enough tracks to accomodate them. When a fixed
position is given, there should be at a minimum a row/column available
for the track. The span will be truncated if there is no space for it
later.
A bug was found where grid items were being drawn outside of the grid if
the item had a large span and the grid was defined as having gaps
between the rows/columns.
This was caused by an erroneous calculation of the
{row,column}_{start,span} properties.
Currently, the generated IPC decoders will default-construct the type to
be decoded, then pass that value by reference to the concrete decoder.
This, of course, requires that the type is default-constructible. This
was an issue for decoding Variants, which had to require the first type
in the Variant list is Empty, to ensure it is default constructible.
Further, this made it possible for values to become uninitialized in
user-defined decoders.
This patch makes the decoder interface such that the concrete decoders
themselves contruct the decoded type upon return from the decoder. To do
so, the default decoders in IPC::Decoder had to be moved to the IPC
namespace scope, as these decoders are now specializations instead of
overloaded methods (C++ requires specializations to be in a namespace
scope).
