Description

I create a folder and upload a file. I then upload an updated version of the file.
Expected behaviour

A pop-up dialog is supposed to appear and let me choose whether or not to overwrite the existing file.
What is happening instead?

The pop-up dialog appears, but then disappears before I can click anything.
Additional context

The dialog appears and disappears too fast to get a screenshot, but I might be able to take a video if it is warranted.
How to reproduce?
