v4.2.2

🐞 Bug fixes

• Android: fixed a native crash (SIGSEGV in OnlineFileSource) under heavy tile traffic — when an HTTP response arrived, the provider removed the request from its pending table before posting the callback onto the RunLoop. A request destroyed in that window (routine with many vector sources loading while panning/zooming or backgrounding the app, where superseded requests are constantly cancelled) couldn't be flagged as cancelled — its destructor found nothing to mark — so the already-posted callback ran against the freed OnlineFileRequest and crashed in mbgl::util::Timer. The pending entry now stays registered until the callback actually executes, and the posted closure re-checks the cancelled flag (it runs on the same RunLoop thread as the request's destructor, making the check decisive).
• Manually opened attribution stays open long enough to read — tapping the collapsed ⓘ chip now pins the banner on every platform: on Android/iOS camera motion no longer collapses it instantly (with GPS-follow active the camera eases on every fix, which swatted the banner shut the moment it opened), and on all platforms (Android, iOS/MacCatalyst, WinUI, WPF) a manually opened banner gets a longer 10 s auto-collapse instead of the standard 5 s. Automatic expansions (style load, attribution content changes) keep the existing behaviour.
