Problem

The top FATAL crash on the google flavor of 2.7.14 is com.google.maps.android.compose.clustering.ComposeUiClusterRenderer.renderViewToBitmapDescriptor — IllegalStateException: Composed into the View which doesn't propagate ViewTreeLifecycleOwner!. It is still present in build 29321006, i.e. after #5704.

maps-compose renders each non-clustered item to a bitmap through an off-screen ComposeView that it attaches under the MapView (ComposeUiClusterRenderer + NoDrawContainerView). That ComposeView walks up the view tree for a ViewTreeLifecycleOwner; when it finds none it crashes. There is no upstream fix as of maps-compose 8.3.0 (latest) — tracked unresolved as googlemaps/android-maps-compose#875 / #325.

#5704 removed the previous workaround because it attached a transient NavEntry lifecycle to the activity root, which caused the node-list popup 0×0 regression (#5684).

Fix

Re-introduce owner propagation, but scoped to LocalView.current (the map screen's host view, an ancestor of the internally-created MapView) instead of view.rootView:

• Sets ViewTreeLifecycleOwner + SavedStateRegistryOwner on the map host view so the renderer's internal ComposeView can resolve them.
• Captures and restores the previous owners on dispose, so Popups/DropdownMenus are left untouched (avoids reopening fix: address top Crashlytics crashes and non-fatals for build 29320984 #5684).
• Keeps a Lifecycle.STARTED guard to skip the cluster renderer's async-Handler render after the screen has stopped.

Clustering(...), clusterItemContent, and the precision-circle clusterItemDecoration are unchanged — no feature regression.

Caveats

• This is a mitigation, not a hermetic seal: the async-Handler-after-dispose tail can only be fully closed by removing the library's ComposeView path entirely (a Canvas custom-renderer rewrite, which would require reimplementing the precision-circle decoration). Filed as a possible follow-up.
• Compile-verified (spotlessCheck, detekt, :androidApp:compileGoogleDebugKotlin all pass) but not runtime-verified here (needs a Maps key + real google-services.json). Suggest a smoke test: zoom to form/break clusters on the map, then navigate back and open a node-list popup to confirm popups still render.
