In my testing, view.store is set if I was previously at a datastore's
"Prune & GC Jobs" but not if I was on a different tab from a datastore.
In both cases, the row does not seem to be selected and the "Edit" and
"Run Now" buttons are still grayed out. So your patch is certainly an
improvement, because there is no error and loading :) But it still
doesn't seem to do what was intended according to the code comment.
