1639664 - ::first-letter/::first-line pseudo selector does not support opacity

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect, P3)

Description

Attachment: first-letter-opacity-bug.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:76.0) Gecko/20100101 Firefox/76.0

Steps to reproduce:

Tried to use ::first-letter pseudo selector and an opacity attribute. See attached file for example.

Actual results:

The first letter's opacity it unaffected by the opacity attribute. It's still possible to change opacity, but only through the color attribute. Unfortunately, this workaround cannot be used in many cases when inheriting color.

Expected results:

Opacity should change.

Hmm, were opacity recently added to the ::first-letter/line specs? Seems odd that we'd miss such a thing...

Same for ::first-line btw:

Anyway, should be an easy fix hopefully:
