FIXES: #7011

Hi Marti @MapTo0 , there is another issues that sounds similar
#7776

The author is trying to call blur so the dropdown closes, because items are not updated while dropdown is open.
However, it's not only for the ComboBox, but for the MultiComboBox as well.

Could you consider the MultiComboBox case as well - could be in another PR, it's just to let you know.

@ilhan007 Just to clarify.
I do not "TRY" to call blur() to close the options. I NEED to, so that I force the options to close after loading, because the options list does not refresh. Calling blur() is the workaround, so the user NEEDS to repoen the options that are then updated.

@timogeib yes, we are aware of that, as you can see, the PR clearly states: "fix(ui5-combobox): update picker items while open", so that you wont need to even call blur or any other method.
