Repro steps:
- During an activity, navigate to map layers, and use the hw buttons to open a layer (eg. popularity routing) and to pin it.
Expected outcome:
- Layer is pinned
Actual outcome:
- Pining the layer (with a start button) also acts as a Stop button. The activity is stopped, but the watch doesn't expect to be in that state, and I ended up on a black screen with a red outline.
- Trying to navigate back to activity via going back to watchface and then to activity has ended in 'new activity' menu, which started a new activity, discarding the previously active activity.
