- Bubbles needs to know if a task has a LocusId for the
Suppress Bubble API
- Apps can already set a locusId on the activity, this
occurs after the activity has been created.
- This CL adds the locusId to the ActivityRecord and
triggers a task info change
- TaskInfo uses the top activity in the stack to populate
the locusId
