This moves LibWeb to using the list of hidden elements from the spec.
Concretely, the following things are now explicitly marked
`display: none` in addition to before:
- elements with the `hidden` attribute
- area
- base
- basefont
- datalist
- param
- rp
The spec also wants `noframes` and `noembed` to be `display: none`,
but since support for frames and embeds doesn't exist yet, these
are omitted for now.
With this, everyone's favorite website http://45.33.8.238/ no longer
displays spans with attribute hidden. (Whitespace handling still
looks a bit off though.)
This makes un-styled text readable when using a dark system theme,
previously such text would be black, regardless of the theme background
color.
Fixes#7274.
In the ListItemMarkerBox render the correct thing when painting.
This covers decimal counting for ordered lists as well as square,
disc, and circle for unordered lists. Thus all currently supported
list-style-types are displayed correctly.
This closes#2059
Text <input> fields will now generate a basic shadow DOM and attach it
to the input element.
The shadow DOM contains a <div> with some inline style, and an always-
editable text node inside it. Accessing the "value" attribute on such
an input element will get/set the value from that text node.
This is really cool, although not super stable since HTML editing is
not super stable. But it's a start! :^)
