skillmap: With the same skillmap open in two places, project doesn't refresh on open

[eanders-ms]

When signed in, with the same skillmap open in two browsers (call them browser A and B), progress in an activity on browser A isn't transferred to browser B when the activity is subsequently opened on B.

Browser B should already be doing a quick cloud check on the project when it is opened. That doesn't seem to be happening. Fixing this isn't sufficient though because skillmap progress must also be synced.

A solution might be to re-sync cloud and skillmap progress when a browser regains focus.
