Setting KeyboardAccelerators on MenuBarItem in Loaded event of user control results in accelerator not working #10977
Description
Describe the bug
See attached repro project. Notice how Ctrl+Shift+D works while Ctrl+Shit+F does not.
Why is this important?
We ran into this after refactoring and suddenly no shortcuts working anymore.
Steps to reproduce the bug
- Create MenuBar inside a UserControl
- Add MenuBarItem in loaded event, add keyboard accelerators
- Hit keys of accelerator on keyboard, observe it not triggering.
In the case of the repro project, Ctrl+Shift+D works while Ctrl+Shift+F does not.
If the menubar is open, the shortcut Ctrl+Shift+F does work, if it is closed it does not.
