Description

When that feature is enabled, the sidebar is "clean" on existing PRs.
Labels are not shown if not defined on the PR.

Issue

I am not able to add a (first) label to the PR once it is created without any label: the gear and the function to add them is not shown in the sidebar anymore.

Notes:

• if there is an existing label, the gear to add additional labels is shown and all works fine.
• No console errors are shown.

Workarounds

1. To quickly add "labels" I use Firefox's "Reload without Refined GitHub" extension's menu (which disables the extension): then the "Labels" section on the sidebar is shown and I can add the first label.
2. When I disable the clean-conversation-sidebar feature I see the "original" sidebar with the labels section.

Wish/Fix

I would like to be able to keep the clean-conversation-sidebar feature enabled, and still add a first label to already created PRs.

How to replicate the issue + URL

1. create a PR on github: do NOT add labels
2. open the PR again, try to add a label

What I see is the following, where I can not add any label

Extension version

26.3.17

Browser(s) used

Firefox 148.0.2 (64-bit)

Token ⚠️
