What changed

• stop pending initialization whenever the view is dropped or its captured source has been superseded
• repeat that guard before background work and again on the UI-thread handoff
• shut down the per-initialization executor in finally on success and every early return

Why

The current checks use viewHasDropped && runningSource == source. That only aborts one narrow combination; a changed source explicitly allows the old request to continue. The old request can then initialize media using a mixture of captured and current source fields. Each attempt also creates a newSingleThreadExecutor() without shutting it down, retaining a thread after its one task completes.

Verification

• yarn build
• yarn lint
• yarn check-android
• git diff --check

The v6 repository has no native unit-test or standalone Android compilation harness; hosted Android CI remains the Java compilation gate.

Breaking changes

None. Only dropped/superseded initialization work is cancelled.
