1950719 - Update all the view transition pseudo element styles

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, task)

Description

[Boris Chiou [:boris]]

We have implemented width, height, and transform when updating pseudo element styles. However, there are still some properties in our TODO list:
writing-mode, direction, text-orientation, mix-blend-mode, backdrop-filter, color-scheme.

Attachment: Bug 1950719 - Update the rest of view transition pseudo-element styles.

Update the styles for writing-mode, direction, text-orientation,
mix-blend-mode, backdrop-filter, and color-scheme.

Also, update the test, pseudo-get-computed-style.html, because it
doesn't really match the spec. For example, we update the pseudo-element
styles after we invoke the update callback, so the computed values of
these pseudo elements should be the default values inside the update callback.

Now the behavior of Gecko is the same as that of WebKit.
