Update on this closed issue: the issue is still there but I've narrowed it down a bit:

The issue (popup not showing) only occurs when I have the Compact Headers extension enabled (https://addons.thunderbird.net/en-US/thunderbird/addon/compact-headers/)
More specifically:

• when I have the headers collapsed, the pop-up does not show
• when I have the headers not collapsed, the pop-up does show

I have no programming experience with Thunderbird extensions, so I have no idea how the two would interact. Nor, which of the two extensions would be the cause of this unintended interaction. Hence, I do not know wha twould be the way forward.

PS: I'm the same person as that opened the original issue (afmoene), I'm just inconsistent with the github account that I use for different tasks.
