/**
 * Walks up from this View to the direct child of the activity's content frame
 * (`android.R.id.content`) and calls `bringToFront()` on that ancestor.
 *
 * On cordova-android ≤14 the WebView is a direct child of the content frame, so
 * the loop exits immediately and this is equivalent to a plain `bringToFront()`.
 * On cordova-android 15+ the WebView is wrapped in an intermediate `rootLayout`,
 * so a plain `bringToFront()` only reorders within that wrapper and is
 * ineffective against siblings added via `addContentView` — the loop walks up
 * to the rootLayout and brings *that* to front.
 *
 * Falls back to a plain `bringToFront()` if the activity can't be resolved
 * (e.g. the View's context is something other than an Activity / ContextWrapper
 * chain ending in one), preserving pre-existing behaviour.
