880a9c9 added the handleAndroidPipChanged and _setPipActive actions to
VideoStoreBase without regenerating the mixin, so neither was wrapped by
the MobX action controller. Both still ran, but their observable writes
landed as separate notifications instead of one batched transaction —
extra rebuilds on every PiP transition. Analyze and the test suite pass
either way; only CI's generated-file diff check catches it.
