User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:103.0) Gecko/20100101 Firefox/103.0

Steps to reproduce:

This issue manifests on Mac OS Monterey 12.5.1

When one clicks on a standard <select> element to open it, it will open but then immediately close again, unless you keep the mouse perfectly still while it opens.

Two example sites are: https://www.safewingatepark.co.za and https://dearsouthafrica.co.za/health-act-amendment/

Click on a drop-down and move the mouse while it opens.

Actual results:

The drop-down opens, but then immediately closes again.

Expected results:

The drop-down should remain open after clicking on it, even if I don't keep the mouse perfectly still.

I can't manage to reproduce the issue on my end.
Could you please try if the issue occurs in safe mode. Here is a link that can help you do that:

Thanks.

I'm getting the same behavior when in troubleshoot mode.

I made videos of the issue on both of the example sites.
