Inconsistent Window Focus Behavior: Debugging vs. Running Without Debugging

Question

In my application, I have a MainWindow that inherits from System.Windows.Window. Within this MainWindow, there's a System.Windows.Controls.Button. Clicking this button triggers the opening of a second window, also inheriting from System.Windows.Window. To display this second window, I utilize the ShowDialog method from the System.Windows.Window class.

However, during debugging (F5), if I click the button to open the second window and then click outside the second window, it loses focus. Interestingly, when running the program without debugging (Ctrl+F5), this issue doesn't occur. In this case, the second window behaves as a modal window, maintaining focus even when clicked outside.

I've already ensured that the second window is set to have the MainWindow as its owner. Despite this, the issue persists. Any suggestions on resolving this discrepancy in behavior would be appreciated.

I have included a link to the project on GitHub for reference.

To work around the discrepancy, try to disable the “XAML Hot Reload” feature in Options dialog (“Debugging” area).
