BUG: Mouse side buttons navigation in Settings causes an unhandled exception

[vzabrodin]

Checks

• I have checked that this issue has not already been reported.

• I am using the latest version of Flow Launcher.

Problem Description

My mouse has side buttons. They can be used to navigate (back, forward) in some apps, like browsers.
When I navigate to Plugin Store, then navigate back and forward using side buttons, the app throws an exception.

To Reproduce

1. Open Flow Launcher's Settings
2. Navigate to Plugin Store (by clicking on it)
3. Use Tab to focus element on navigation view (by pressing Tab for many times until it does not focus on page elements) Or Put mouse cursor must be hovering navigation bar's content
4. Navigate back using mouse side button.
5. Navigate forward using mouse side button.

Screenshots

I noticed that selected page in sidebar is not updated when I navigate using side buttons.

On screenshot below Plugin Store page is selected but General page is displayed.

The exception should be resolved in #3311 already.

@vzabrodin Thanks for your report! Could you please check if it is fixed in #3547?

No exceptions now. But it doesn't work as expected.

I have to press back twice to navigate to previous page. And forward doesn't work at all.

(I compiled the app manually from setting_window_navigation_issue branch)

Could you please check default behaviour in dev branch?

dev branch:

System.NullReferenceException
  HResult=0x80004003
  Message=Object reference not set to an instance of an object.

Sorry, I mean the navigation behaviour in dev branch. I think I have not changed the navigation behaviour in that PR. But you found back twice issue & forward issue.

[vzabrodin]

Navigation in dev branch throws an exception, like in published version (1.19.5). And it doesn't have back twice issue & forward issue.
