When using keystrokes (select all, right arrow) to expand folders in the sync preview window, action icons are lost. Cyberduck 7.6.1 (33485), Mac 10.15.7 (19H2). Please see attached screen shots to see the results:

Steps to reproduce:

1. Start a mirror synchronization between a local and remote dir where a local file has changed.
2. Click the root item's triangle to expand first level dirs. 1.png and 2.png . Notice that the action icon (an up arrow in my case) is correctly shown.
3. Click the root item itself to select it (necessary for keystroke focus).
4. Type command-a (select all) then right arrow to expand all.
5. Scroll down to the changed file and notice that the up arrow is gone. 3.png
