A UI bug on iOS devices: iOS native window is shown after focusing on a multiple choices select element

Steps to reproduce:

1. Open the following page from an iPhone: https://select2.org/appearance#labels

2. Focus on the multiple select element field.

You'll see that the 2nd iOS native window saying "No Options" is temporarily shown (just for a second):

I've tested on 2 iPhone devices with different iOS versions. The bug persists.
