4323669939 LibWeb: Add Range::for_each_contained() 
This centralizes the logic for iterating over a Range's contained nodes.

2466021e55 LibWeb: Rename argument to split_the_parent_of_nodes() to reflect spec 
The spec calls it a "node list", not "nodes".

f4c822ee38 LibWeb: Simplify fix_disallowed_ancestors_of_node()'s usage of node 
Commit 98df4c2b changes the node argument to a GC::Ref<DOM::Node>, but
not all usages were updated accordingly.

bd2488a468 LibWeb: Make block_extend_a_range() take a GC::Ref for the range 
This makes it more consistent with the other signatures.

c0285f4a7e LibWeb: Do not require visible nodes in the wrap editing algorithm 
The spec doesn't say they should exist, so we should not
`VERIFY_NOT_REACHED()` when they don't. Prevents a crash in the WPT
`editing/event.html` tests.

e6631a4216 LibWeb: Add concept of boundary point to DOM::AbstractRange 
This makes comparing the relative position of boundary points a bit
nicer when one of the boundary points is the range's start or end.

2c51ed8dec LibWeb: Rework obtaining resolved styles in the Editing API 
The algorithm referenced to in the Editing spec whenever they talk about
obtaining the "resolved" style or value is actually implemented in
ResolvedCSSStyleDeclaration, so use that instead of going directly to
the computed styles.

1c55153d43 LibWeb: Refactor "editable" and "editing host" concepts 
The DOM spec defines what it means for an element to be an "editing
host", and the Editing spec does the same for the "editable" concept.
Replace our `Node::is_editable()` implementation with these
spec-compliant algorithms.

An editing host is an element that has the properties to make its
contents effectively editable. Editable elements are descendants of an
editing host. Concepts like the inheritable contenteditable attribute
are propagated through the editable algorithm.

f88c13a58c LibWeb: Prevent null deref in collapsed whitespace check 
The spec even warned us about the reference potentially being null.

e308a3fd3f LibWeb: Be more defensive while traversing ancestors in editing API 
In all these cases there should be an ancestor available, but it
definitely cannot hurt to be a bit more defensive about this and prevent
nullptr dereferences.

b6939c8035 LibWeb: Use wrap algorithm in "fix disallowed ancestors" 
We have the wrap algorithm implemented now, so resolve the FIXME.

2e29d3fb57 LibWeb: Fix is_allowed_child_of_node() for non-element parent node 
When passing a DOM::Node that is not a DOM::Element, this method would
always try to cast to a DOM::Element.

7e406ac668 LibWeb: Simplify editing algorithm for "ends in space" condition 
Checking if a string ends in a space does not require converting UTF-8
to UTF-16 and reading out its code points.

7bb865052a LibWeb: Implement document.execCommand("delete") 
To facilitate the implementation of "delete" and all associated
algorithms, split off this piece of `Document` into a separate
directory.

This sets up the infrastructure for arbitrary commands to be supported.
