Is your feature request related to a problem?

In a desktop app with a menu the menu shortcuts are still active while a dialog is open. This can be a problem, because if there are shortcut that opens a dialog (e.g. a settings dialog), this allows the user to open multiple instances of the same dialog, one on top of each other. It may also be weird for users to be able to open menu items through shortcuts while a supposedly modal dialog is open. In general this behavior breaks the expectation of modality for dialogs in desktop apps.

Is it possible to construct a solution with the existing API?

As a workaround one could manually remove all menu shortcuts before a dialog is open and re-add them again when it is closed. This would have to be done for each and every dialog in the app and would result in a lot of additional boilerplate code.

Describe the solution you'd like to see.

Menu shortcuts should be automatically disabled when a dialog opens and re-enabled when it is closed. Any other shortcuts should not be affected.
