Select2 not working on Safari browser

Select2 version: 4.0.13
Tested with ios 13.3 and 14.1 on iPhone6s, iPhone 8 and iPhone 11 Pro as well as Mojove, Catalina and Big Sur

It appears the dropdown does not function on Safari on either desktop or mobile?

When it is tapped, nothing happens except for the border being highlighted (in the screenshot the blue border is not there until it is tapped)


Thank you
