Not sure if related, but this is reproducable on RTL.

(In reply to Itiel from comment #1) > Not sure if related, but this is reproducable on RTL. When testing RTL by setting intl.uidirection to 1 in about:config, I see something that looks like the screenshot from bug 1504236, and I'm fixing these issues, but I still don't reproduce this bug.
I can reproduce this, by resizing the window(making it smaller than the list) or having the list of tasks exceeding the window height. See my attachment.
Also, there's another UI issue, if I resize the window width to be smaller- "Type" overlaps the "Name" field and task names are no more visible. See my second screenshot.

See my > attachment. Thanks! Your attachment 9023000 [details] also shows a useless vertical sidebar (I noticed this on Windows and Linux yesterday evening).
Summary: Column text is offset to the left and not aligned with headers → Column text is offset to the left and not aligned with headers when there's a vertical scrollbar
- Fix the misalignment between the header text and the body text when there's a vertical scrollbar (this is fixed using position: fixed for the header and making the scrollbar apply to the whole table rather than just the body). - Avoid the useless vertical scrollbar on Windows. This was due to a problem on the line "height: calc(100vh - 2em - 1px);" that I'm removing. "2em" was actually not enough to account for the size of the header, as the size of the header is max(2em, 2*line-height)... which ended up being 1px more than 2em on Windows. - Avoid the issue of the Name column being so small that the 'Name' label would overflow into the next column. I fixed this by giving the whole table a minimum width of 40em. The header (which is positioned, so sized independently) also need the min-width rule. When resizing the window to a size smaller than 40em, an horizontal scrollbar was appearing, but made only the table body scroll, as the header has a 'fixed' position. I couldn't find a good fix for that, and such a tiny window is so useless anyway that I decided to just hide the scrollbar in that case (that's the reason for the overflow-x: hidden on the body). I tested this on Mac and Windows. If you r+ I'll test on Linux too before landing.

Comment on attachment 9023693 [details] [diff] [review] Patch [Beta/Release Uplift Approval Request] Feature/Bug causing the regression: new about:performance User impact if declined: Broken/misaligned layout. On Windows, a useless vertical scrollbar. This bug also turned out to be the cause of the frustrating bug 1504839. Is this code covered by automated tests?: No Has the fix been verified in Nightly?: No Needs manual test from QE?: Yes If yes, steps to reproduce: Given that this changes several CSS rules, it would be good to verify that the layout is still correct with various themes, and maybe also various font sizes. List of other uplifts needed: 1503680 (just so that the patches land in the same order on beta) Risk to taking this patch: Low Why is the change risky/not risky? (and alternatives if risky): Low because CSS only, and brokenness (if any) should hopefully be visible quickly. String changes made/needed: none

I've managed to reproduce this issue using Firefox 65.0a1 (BuildId 20181101220058) on Windows 10x64. This issue is verified fixed using Firefox 65.0a1 (BuildId 20181114222927) on Windows 10x64. Note: It seems that after resizing the window to its minimum width, the horizontal scrollbar does not appear. Is this an intended behavior, if not, please let me know and I will file a bug for that issue, separately?

This is an expected side effect of the patch, yes. If I didn't hide the horizontal scrollbar, the body of the table was scrolling horizontally but not its header, which was worse than not scrolling at all.
This issue is verified fixed using Firefox 64.0b10 on Windows 10x64.
