Suggestion menu, when opening on top, isn't positioned correctly #2155
Description
Describe the bug
When opening any suggestions menu, if there's not enough space on the bottom and it opens on top, if the menu only has a few items, it is placed far above the cursor.
It appears the suggestions menu has a min-height of 300px. If the menu's items are few and thus the menu is shorter than 300px, the menu appears too far above. Not sure why the 300px min-height is added but it causes this issue and there's no way to override it since its added as a style attribute not through a class.
You can reproduce this issue with the / menu by simply filtering down to a small number of items.
