Owncloud integrates CODE 6.4.1103 - CALC drop down list not usable with mouse

Hi there,

we’ve just updatet to 6.4.1103 on nextcloud 20.5 / ubuntu.
When using a drop down list for chosing items from a list. (From the menu Daten/Gültigkeit in German) and use the mouse to scroll the list up and down, the list will collapse as soon as I release the mouse button.
So there is no chance to choose the list item.

The behavior does not seem reproducible on my end.

@MVZ-LRA, Please can you share a sample file?
