How to replicate (e.g. in demo/All Data Types):
- Switch to grid view
- Add a new row
- Select an entry from a drop-down field
- Make the column shorter than the text which is now visible in the grid cell
- Try to open the dropdown again in order to select another value
The drop-down will flicker and not open (sometimes it opens on double-click). If you make the column wider than the text, it will work again.
Desired behaviour: The drop-down should always open.
