Menu is offset incorrectly

[Pytal]

How can we reproduce this bug?

1. On a Nextcloud instance open the Files or Photos app
2. Choose a file
3. Open a sidebar
4. Go to comments-tab
5. Reduce viewport width to around <1100px
6. Type @ in input field to search for available users
7. See that the dropdown menu is on a left side and is not visible for user

What did you expect to happen?

Menu is fully visible

What happened instead?

Before reducing the width

After reducing the width the menu is offset to the left

Cause

This appears to be caused by the positioning code

tribute/src/TributeRange.js

Lines 527 to 573 in 252ec34
