I tried to create tests as well for whether the face pile on the poll options is hidden when the room has more than five members, but I found it very hard to do without relying much on implementation detail.

I'm also open for other approaches to opening the detailed result list. One idea might be to make a separate, underlined span that just says "Open full results" next to it.

Strict mode commit was temporarily reverted because of #28306

Also found the time to add an end to end test for the vote results dialog. If there is anything else that I can do to progress this PR further, please let me know.

I see this has been sent to design & product for review, but I'm not really sure what this PR is trying to do. A description, linked bug and screenshot would help.

That said, I suspect the answer from product will be that polls need to stay consistent between clients, so if this makes web display more than Element X, we'd also need to make corresponding changes there and land them around the same time.

Oh sure. Damn I wanted to do that but forgot it again. Will do.

Okay. I will take a look if I can manage to do that.
