Description

Upstream issue https://issues.gerritcodereview.com/issues/346174905


Steps to replicate the issue (include links if applicable):

  • Use Firefox 126 (stable) or Firefox 128 (nightly)
  • Open a Gerrit patch
  • Select some text on *file* in a patch

What happens?:

The "press c to comment" button is either at the bottom of the page, or below the viewport, and thus looks like it is not present at all.

Browser console messages (not relevant):

What should have happened instead?:

I should see a dialog for adding an inline comment next to the line or region that I've selected.

Other information (browser name/version, screenshots, etc.):

Firefox 126 or Firefox 128 on macOS

Note that commenting on commit messages in a patch works, but the "Add comment" button is placed in an odd location

kostajh added a subscriber: hashar.

so, it looks like the element is added to the page, but it's not visible in the viewport. If I press "c", then the comment box appears.

Indeed, there it is, you have to scroll down to the very bottom of the page to find it.

I see the same behavior on upstream Gerrit, e.g. when trying to comment on https://gerrit-review.googlesource.com/c/k8s-gerrit/+/409747/23/container-images/gerrit-init/tools/gerrit-initializer/initializer/helpers/git.py#55

With Firefox 115:

I can confirm the Popup shows up at the wrong position. The element <gr-selection-action-box> is after the element commenting the diff and its top position move it way below. If I manually change the css position from absolute to fixed it is a bit better but still off.

If I press C, the comment window shows up at the proper position.

With Chromium 124, the popup is at the proper position. I have to press C to insert a comment for the selected text.

Same behavior on upstream instance which runs 3.10.0-rc7 ( https://gerrit-review.googlesource.com )

Here's what it looks like on Chrome:

Compared with Firefox:

Yes the CSS positioning is off somehow. The element has position: absolute but under Chrome that is relative to the top of the diff while on Firefox that is relative to the bottom of the diff element. I don't have any good candidate nor could I find a way to fix the CSS through the inspector. I am afraid I will have to bisect it.

At a quick glance at polygerrit-ui/app/embed/diff/ they have changed the diff view and moved from a table layout toward a grid one. Firefox must have some slightly different behavior.

I get it fixed by adding style="display: block" to the parent element <gr-diff-element> but that not be the proper way to fix it.
