- Comments created by means of a tag closer with an invalid tag name, e.g. `</3>`.
- Comments closed with the invalid `--!>` closer. (Comments should be closed by `-->` but if the `!` appears it will also close it, in error.)
- Empty tag name elements, which are technically skipped over and aren't comments, e.g. `</>`.

When setting a new value for an attribute multiple times and providing
multiple case variations of the attribute name the Tag Processor has
been appending multiple copies of the attribute into the updated HTML.
This means that only the first attribute set determines the value in
the final output, plus the output will //appear// wrong.
In this patch we're adding a test to catch the situation and resolving it
by using the appropriate comparable attribute name as a key for storing
the updates as we go. Previously we stored updates to the attribute by
its given `$name`, but when a new update of the same name with a
case variant was queued, it would not override the previously-enqueued
value as it out to have.

In this patch we're adding `has_self_closing_flag()` to the HTML Tag Processor.
This exposes whether a currently-matched tag contains the self-closing flag `/`.
This information is critical for the evolution of the HTML API in order
to track and parse HTML structure, specifically, knowing whether an
HTML foreign element is self-closing or not.

While `WP_HTML_Tag_Processor` currently only supports changing a given tag's attributes, the plan is to provide methods to make broader changes (possibly through a subclass of `WP_HTML_Tag_Processor`). The API will have the potential of replacing a tag that a bookmark points to. To prepare, this changeset makes sure that all bookmarks affected by a HTML replacement are invalidated (i.e. released).
Changes:
* Extends the existing loop in `WP_HTML_Tag_Processor::apply_attributes_updates()` that adjusts bookmarks' start and end positions upon HTML changes to check if the entire bookmark is within a portion of the HTML that has been replaced.
* Adds `WP_HTML_Tag_Processor::has_bookmark() to check whether the given bookmark name exists.

Documents the shorthand usage, i.e. `$this->next_tag( 'img' )`, of `WP_HTML_Tag_Processor::next_tag()`.
Also includes table alignments and formatting adjustments in the class docs.

Setting a bookmark on a tag should set its "start" position before the opening "<", e.g.:
{{{
<div> Testing a <b>Bookmark</b>
----------------^
}}}
The previous calculation assumed this is always one byte to the left from `$tag_name_starts_at`.
However, in a closing tag that index points to a solidus symbol "/":
{{{
<div> Testing a <b>Bookmark</b>
----------------------------^
}}}
The bookmark should therefore start two bytes before the tag name:
{{{
<div> Testing a <b>Bookmark</b>
---------------------------^
}}}
This changeset achieves this by:
* Using the correct starting index for closing tag bookmarks.
* Adding `array( 'tag_closers' => 'visit' )` in `WP_HTML_Tag_Processor::seek()`.

When the HTML API was introduced a number of fields were switched from private visibility to protected so that Gutenberg and other systems could more easily enhance the behaviors through subclassing. The $this->html property was overlooked but important for systems using the Tag Processor to stich HTML, specifically performing operations on innerHTML and innerText.

This commit pulls in the HTML Tag Processor from the Gutenbeg repository.
The Tag Processor attempts to be an HTML5-spec-compliant parser that provides the ability in PHP to find specific HTML tags and then add, remove, or update attributes on that tag. It provides a safe and reliable way to modify the attribute on HTML tags.
