Drop down's selection area bug!

Hi,
When there is a Unicode character in the dropdown options, it will often can not be selected,it is normal when there is no Unicode character.
The version of lvgl is master,and the code is lv_ex_dropdown_1()
Like the gif:

@kisvegabor Any idea why this happens? It seems to be triggered by selecting an already selected Unicode option.

Hi,

I’ve fixed in in master.
