DropDown List Selection Firefox bug

Hi,

I noticed a strange behaviour of the UI. When trying so select an item from a DropDownList (e.g. Selection of Shipping Address) the control does not respond in the first place. Only the second click opens the lists. That behaviour is only in FireFox (newest version 93), in Edge it works.

I use the Nop 4.40 on windows.
Can anybody confirm this behaviour?

Yes facing the same issue in Firefox(desktop).

Yes it is Firefox for Windows Desktop. Anybody an idea how to debug that?

What I found out so far:
- The error is specific to nopCommerce, because other sites work well
- I disabled all CSS for the html 'selection' and 'option' tags, but the error still shows up
- it seems that the first click activates the drop down list, and the second expands it eventually
- my guess is, that some of the javascript code is responsible for this behaviour

Thanks, here is a work item for this.
