Observed behavior
The offline indicator that shows in the channel editor is also showing on the sign-in page.
Expected behavior
I'm not sure this indicator should be visible since we recently added an offline message to the actual form.
User-facing consequences
The indicator's tooltip text shown on hover is confusing in the context of the sign-in page, as seen in the screenshot
