Steps to reproduce:

open https://github.com/Rooyca/MarkOb-Obsidian-Highligter
try to copy all table columns within first table.

we were able to narrow the builds
last good

first bad

Sören Hentzschel second the builds and pointed out that this time Intl.RelativeTimeFormat and Intl.DateTimeFormat were completed around that date.

currently any build after that date is not able to copy the whole table data

Actual results:

result: you can mark first and second column, but not third, marking (date) goes wild.

Expected results:

expected: marking all three columns (like firefox 73 did, chromium based do)

[BugBot [:suhaib / :marco/ :calixte]]

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

To clarify since there was a little misunderstanding: I don't know if there is a relation between these APIs and the reported problem. I just wanted to clarify in the linked forum post that the fact that the relative timings in the earlier builds did not work could mean that some parts of the used APIs were implemented in a later Firefox version (I have not checked that). I also have not debugged whether there is a relation between the non working relative timings in previous builds and the broken table selecting in later builds. I only confirmed that I also got a change in the Firefox 74 timeframe as regressor and that mozregression was not able to bisect further.

I'm confused, I don't see any table, you mean the file list? Which is sorta similar?

If so, the time is in shadow DOM, so this is basically bug 1455893.

Yes, the reported issue was about the file list.

If so, the time is in shadow DOM, so this is basically bug 1455893.

Thanks for the reference!
