Comment 1

[BugBot [:suhaib / :marco]]

The Bugbug bot thinks this bug should belong to the 'Core::DOM: Selection' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Comment 2

[Šime Vidas]

The ::selection pseudo-element is already supported in Firefox, so it can probably be removed from this bug’s title.

Comment 3

[Sebastian Zartner [:sebo]]

While ::target-text is a highlight pseudo-element, it is quite different from ::spelling-error and ::grammar-error. So it should probably be moved into its own bug. What do you think, Daniel?

[Emilio Cobos Álvarez [:emilio]]

This bug is probably fine, we can file dependent bugs if we're only going to implement some of them.

Comment 5

[Nicolas Chevobbe [:nchevobbe]]

::target-text was implemented in Bug 1867939

Comment 6

[Boris Chiou [:boris]]

This is a subset of Bug 1703963, so I tweak the dependency a little bit.

Comment 7

[Thomas Wisniewski [:twisniewski]]

Given comment #5, I'll remove target-text from the bug title.
