Qt 5.15.3 / Samsung S10e 10.0, Emulator 10.0

Steps to reproduce:

1. Run example 'gallery' project.

2. Open drawer and select ComboBox page.

3. Select any option from editable combobox and then tap on the arrows to reveal the list again.

Actual: Text is duplicated and doing the same again it's duplicated again. See the attached video Screen Recording 2021-02-18 at 13.30.41.mov

Expected: Text should stay the same if user did not edited it.
