1853135 - Link color override ignored when color:highlight is used in css

Status: NEW

(Core :: CSS Parsing and Computation, defect)

Description

[Aivars]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/117.0

Steps to reproduce:

In settings -> manage colors
Override the colors specified by the page with your selections above = Always
changed Link colors to my prefered

Actual results:

mostly it works as expected unless in CSS color:highlight is used
for example github.com uses color:highlight for links
and links are colored dark blue instead of using colors defined in Settings -> Manage colors

Expected results:

all links should be colored using colors defined in Settings -> Manage colors with overrides enabled
color:highlight should not impact link coloring

The Bugbug bot thinks this bug should belong to the 'Core::CSS Parsing and Computation' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Attachment: Mimimum Reproducible Case

Following the reporter's steps of with the attached test case, by:

1. Launch the test case and observe link colors
2. Go to Preferences - Manage Colors
3. Set link colors to something non-default
4. Set "Override the colors specified by the page with your selections above" to Always
5. Observe link colors again

I can confirm that color: Highlight & color: MarkText links do not change in color on 118.
Both happen to be System Colors.

This is per spec. hcm respects all system colors (including Highlight).

You can fix this with a user stylesheet like a { color: LinkText !important; } a:active { color: ActiveText !important } a:visited { color: VisitedText !important }.
