Revision ec35b03ca5e8eec6eb1767a77f0aea13855515a3 authored by Rune Lillesveen on 29 June 2018, 22:17:37 UTC, committed by Blink WPT Bot on 29 June 2018, 22:26:52 UTC
We used to create these pseudo elements and their computed styles in Element::AttachLayoutTree when building the layout tree. Now we create or dispose these elements from style recalc, that is, UpdatePseudoElement. To make pseudo elements live through a style recalc with a layout tree re-attach we no longer clear the pseudo elements during DetachLayoutTree for performing_reattach=true. We do however need to clear the pseudo elements which do not get a layout object for the re-attach. That is done in AttachLayoutTree for the originating element when the originating element does not generate a layout box. We stop using the pseudo style cache on ComputedStyle for PseudoElements and instead return the ComputedStyle when creating the pseudo element and store it as non-attached style which can later be retrieved when attaching the layout object. An effect of this change is that we can detect transitions on pseudo elements when ancestors display types changes and causes re-attachment. That is issue 836140. ::first-letter may still be generated during layout tree building, and the ::first-letter layout structure may still be updated during style recalc.

The test is passed if:

<li>
Each letter in the word "ROTATE" is rotated 10
degrees more than the previous letter, with the first letter being
rotated at 0 degrees.
</li>
<li>
Each letter in the word "Multi XY" (including the white space) is
shifted in the x and y by 20 pixels more (in user space) than the
previous letter, with the first letter beginning at coordinate

<li>
Each letter in the word "Both Together" (including the space) is
rotated and shifted. Each of the rotated letters is rotated -10
degrees more than the previous letter, with the first letter being
rotated a 0 degrees. Each of the shifted letters is shifted by 20
