change: Log the trigger for a refresh/reload (#466)

A user is reporting that a refresh is happening in the middle of loading
content, borne out by the existing logs.

Those logs don't say what has triggered the refresh attempt, so add
additional logging whenever a refresh can occur to record what triggered
it.
