Some steps are still to be implemented, namely:
* Properly aborting the read algorithm
* Handling BinaryString type properly
* Setting error on any error
But as it stands, this is enough functionality for the basic case of
reading the contents of a blob using the FileReader API.
ArrayBuffer no longer stores a plain ByteBuffer internally, but a
DataBlock instead, which encapsulated the ByteBuffer together with
information if it is shared or not.
This adds initial support for `open-quote`, `close-quote`,
`no-open-quote` and `no-close-quote`. We don't yet track the "nesting
level" so we always use the first pair of quotes from the `quotes`
property.
After moving to navigables, we started reusing the code that populates
session history entries with the srcdoc attribute value from iframes
in `Page::load_html()` for loading HTML.
This change addresses a crash in `determine_the_origin` which occurred
because this method expected the URL to be `about:srcdoc` if we also
provided HTML content (previously, it was the URL passed along with the
HTML content into `load_html()`).
This allows us to get rid of property_table_ordered() which was a
heavy-handed way of iterating properties in insertion order by first
copying them to a sorted Vector.
Clients can now simply iterate property_table() directly.
3% speed-up on Kraken/ai-astar.js :^)
Fixes regression introduced in b4fe118dff
The `WebContentConsoleClient` needs to be created not just once, but
for every new document. Although the JS Console window allows
communication only with the active document associated with the
top-level browsing context, we still need a console client for each
iframe's document to ensure their console logs are printed.
In the future, we might consider adding the ability to switch which
document the JS Console window communicates with.

If `load_document()` is called with a response that has a mime type we
can't use to build a document, we should return nullptr as the spec
says, instead of crashing. Also we should not crash if error happened
during parsing.
This fixes issue reproducing with following steps:
1. Node::insert_before() adopts a node into another document.
2. Node::insert_before() runs insertion steps for adopted node (adopted
node style is not invalidated yet).
3. Insertion steps execute spin_until() on event loop.
4. The next task on event loop does Document::update_style() which
requires layout tree rebuild.
5. Layout tree rebuild fails because there is a node with invalidated
style.
This is not in the spec, but we need to make sure that "apply the
history step" for initial navigation to about:blank in iframe is
applied before subsequent navigations. Otherwise, "set ongoing
navigation" call during "about:blank" traversal might abort subsequent
ongoing navigation which is not expected to happen.
During the destruction of a navigable, we need to use the pointer to
the navigable that was saved at the beginning of the function. This
is because `Node::navigable()` will return a nullptr in subsequent
steps after the navigable's document becomes inactive.
