1. Right click the table cell and choose "Cell" -> "Cell properties" from the context menu.
2. Click the 'Choose' button for the background color.
3. Pick any color and click Ok.

## Expected:

* The color is picked and the color picker closes correctly

## Unexpected

- The color is picked but the color picker overlay stays which makes the app unusable.
