[OPEN] [#335] Cell stays selected after clicking button

[stratadev]

I can reproduce my issue using your CellEditing example: https://examples2.ext.net/#/GridPane...s/CellEditing/.

1. Click on a cell
2. Click 'Add Plant'
3. Click on a different cell from the one you clicked on first

Notice the first cell does not lose its selected style.
You can repeat the above and have many selected cells where only one should ever be selected.

Thanks,
Ryan
