Unit selection for files question not working correctly

[Chartman123]

While testing file upload questions, I noticed another issue that may be related to usability.

When configuring the maximum file size for a file upload question, the unit selector (kB / MB / GB) does not work correctly. The dropdown opens, but I am unable to change the unit. It remains unchanged and appears to result in an error.

I am not sure whether this is a bug or related to my setup, but I wanted to mention it here in case others experience the same problem.

@Koc could you please look into this one? Probably easy to fix and a regression coming from the vue3 migration :)
