I went ahead and removed a wrapping div which looked redundant to me. Feel free to revert though if I missed out on something.

E2E tests are failing though, and I'm not quite sure why yet.

It appears to me, that this fixes an old problem I didn't know Qalendar had - namely text overflow from week events. At least sometimes when they're very short. That seems to be the reason the screenshot tests failed.

I can't record new linux screenshots based on this branch, because it's in your repo. Would you mind trying to trigger the record snapshots workflow in your fork, throw out the old linux folder and add the linux folder from the resulting screenshots in your fork?

If it doesn't work out please let me know, then I can open up a new branch based on yours and record the screenshots.
