#1143 [Context Menu] All the items of any submenu are not working after calling menu via CTRL + Key_Menu

[John]

When I click on the right mouse button on the free space and then the context menu is being called, all the items are working: items in the main menu and the ones in submenu (like Create New -> Folder, Empty File; Sorting -> By Name, etc.). When I call context menu using CTRL + Key_Menu then not any item is working. Items in the main menu are doing correctly, but those in submenu (Create New -> Folder, Empty File; Sorting -> By Name, etc.) doing nothing.

Context file menu:
If for some mime-type multiple apps defined to open with: then such apps are combined in the submenu "OpenWith". And when context menu is calling by right mouse button - every item in a such submenu is working fine. The same file menu (sub items) aren't working after pressing CTRL + Key_Menu clicking on app that is located in that submenu.

So... For some reason only the sub-items aren't working after calling menu via CTRL + Key_Menu (items in the main menu are working), but everything works fine after right mouse button click.

Moving the subitems into the main context menu for some reason is making them working via CTRL + Key_Menu:

in /libfm/src/gtk/fm-folder-view.c

For example moving item Create New -> Dir into just Create New Dir
Create New -> Empty File into just Empty File

The bug appears in the recent libfm versions only - It's working nice in Lubuntu 18.04.
