My channel was too small to see this happen in manual testing, but the code changes are very straight forward, and the screenshot removes all doubt!

@bjester is there anything that can be done so that the sync progress can be visible even for the smallest channel being synced? From a user point of view it still looks as though nothing is happening at all - perhaps there should be a text message similar to the one being displayed after successfully having published a channel - "Published 19 hours ago" - which can remain visible for some time.

@pcenov I added this issue for consideration from our design team.
