Shortcut that opens/closes window does not refresh taskbar

[Gabriel-Darbord]

When using a shortcut that opens a window, the corresponding tab is not immediately added to the taskbar.
This does not happen when using the context menu.
The opposite happens when using the cmd+w shortcut to close a window, then it is not immediately removed from the taskbar.

To Reproduce:

1. Use a shortcut that opens a window, e.g. cmd+o+b
2. Notice that the tab does not appear on the taskbar
3. Trigger a refresh, e.g. by moving the mouse
4. Now the tab appears

Version information:

• Pharo Versions: 13, 12, 11, 10 (didn't check further back)

This is probably due to the unclose window features.

And this is worse than that. Even when not using the Unclose last closed window when we close a window it does disappear from the taskbar.

The fact that opening w shortcut makes it appear on a taskbar until you move your mouse has been there since Pharo12

This actually goes back to Pharo 10 and maybe even before, I'm surprised I never noticed until now 😲 (or at least never made an issue and forgot)
