Bug#962443: Issue not in Thunar 1.8.14-0ubuntu1; potential fix in commit

[Karl Voit <debian@Karl-Voit.at>]

Hi,

I could not reproduce the issue with an up-to-date Xubuntu 20.04 LTS
which is featuring Thunar 1.8.14-0ubuntu1.

So I took a quick look at the commit history of the project. I found a
potentiel commit candidate that provides a fix for the issue reported:

| Ensure user customizable action uses currently selected file path (Bug #15119)
| 
| Moves the call to thunar_standard_view_merge_custom_actions from thunar_standard_view_context_menu
| to thunar_standard_view_selection_changed to ensure that the available menu items get updated
| whenever the file selection changes, not just when a context menu is run.
