[Bug]: Back nav issue with Explore tab object details

Checklist

• I have updated to the latest available Frigate version.
• I have cleared the cache of my browser.
• I have tried a different browser to see if it is related to my browser.
• I have tried reproducing the issue in incognito mode to rule out problems with any third party extensions or plugins I have installed.

Describe the problem you are having

The browser back action has unexpected behaviour while viewing an object in the explore tab.

As the selected object appears as a dialog, you would expect the back action to dismiss the dialog, instead it navigates back "behind" the dialog, keeping the dialog visible and on top of the stack. The only way to dismiss the dialog is using the on-screen back button (mobile) or X (desktop). And when this occurs you've lost your navigation state/filters on the Explore tab.

This issue is most prominent on mobile as I use Android with gesture navigation which triggers the browser back action. I assume iOS is similar. It's easily reproducible on desktop too.

Steps to reproduce

1. Navigate to the Explore tab
2. Select a label, e.g. car
3. Click an individual object to see the object details
4. Click browser back button
5. Observe object details remains visible
6. Click on-screen back/X icon
7. Observe object details dismissed, and car filter has been removed

I don't expect this issue is specific to my installation or configuration, appears to be a basic frontend bug

Clicking the browser's back button on desktop browsers to dismiss a modal is not typical UX, but this has already been fixed for mobile devices for the next version of Frigate in #17685

Thanks for the quick reply and yeah mobile was my only concern, it was just easy to repro on desktop too.

FWIW I still think that is a bug on desktop. You can see the page behind the dialog change, and some devices like mac trackpads have gestures for back navigation that some people may prefer to use.

While I wouldn't consider it a "bug" in that functionality is broken, it could probably be at least undesirable behavior.

I've put up a PR to improve it here: #17932
