Can't add labels to PRs or issues that lack labels when Refined Github is enabled

[CodingCanuck]

Description

When Refined GitHub is enabled, clicking on Labels (or the corresponding gear icon) does nothing:

When I disable Refined GitHub, clicking on Labels shows the Labels dropdown:

I've confirmed with my coworkers who also use Refined GitHub that labels were working yesterday.

I see that yesterday the 22.7.20 release was pushed: https://github.com/refined-github/refined-github/releases/tag/22.7.20 could this be a regression in the latest release?

How to replicate the issue

Open a PR or issue which:

1. you have permission to add labels to
2. has no existing labels

For me https://github.com/3rdparty/eventuals/issues/483 reproduces this (since it has no labels and I have permission to add labels) but https://github.com/3rdparty/eventuals/issues/456 does not (I have permission, but when there are existing labels the labels modal works correctly)

Extension version

22.7.20

Browser(s) used

Chrome

Feature bisector points to clean-conversation-sidebar being the culprit.

@CodingCanuck You can disable that specific feature until this is fixed :slightly_smiling_face:

Confirmed: disabling that feature is a workaround for this issue.

That feature points to https://github.com/refined-github/refined-github/pull/5777/files as a potential culprit, could that be the regression?

I'm not familiar with this code, but I'm suspicious of the > being dropped from the line under // Hide heading in any case except `canEditSidebar\`

I disabled it via hotfix again, we had just fixed it
