When moving to a dropdown item in a database grid and pressing ALT+Cursor Down there should be a list of items to select.
In Libre Office 6.5 this still worked. Now the only way to open the dropdown list is to click with the mouse on it.
Could confirm the buggy behavior with LO 126.96.36.199 on OpenSUSE 15.1 64bit rpm Linux.
Opening the Listbox with Alt + Down works well in LO 188.8.131.52. So this is a regression.
Not sure what the databse grid is exactly, I checked this bug in the Table Design window, with Field Type column.
This started with the same commit as bug 135641. Marking as duplicate.
