Hey @AndiAJ thanks for posting this! I see the exact same bug in the latest versions of the reference-browser (based on android-components v115). I also see this bug in my application, Ceno Browser which also depends on android-components (currently on v113.2.0).

I would really like to see this bug fixed, since it also causes behavior where user input text is deleted randomly while they are typing. I understand that Fenix doesn't really depend on the BrowserToolbar component, instead it implements its own (extremely complicated) toolbar, so I'm guessing that's why this has not been fixed.

My initial guess is that this is related to the ToolbarFeature component, possibly with the way the ToolbarPresenter updates the displayed url, maybe around this line. Any advice from mozilla developers would be greatly appreciated.
