Update from esr68-based Tor Browser to a new esr68-based Tor Browser shows red dot while downloading

Contrary to what we see with updating a stable version, if I update an alpha release based on esr68 to our latest alpha release (assuming I am actually using an older version in the first place, like 9.0a7) then the process of downloading the update is accompanied with a red dot on the hamburger menu which seems unnecessarily scary, compared to the green arrow we show in the stable series.

Looking closer at what is happening by opening the hamburger menu during that process indicates that maybe an icon is actually missing here as there is no red dot shown in the menu itself, just no icon at all after the message that the update gets downloaded. Once that is done the green arrow icon shows up for a restart, both on the hamburger menu as within it, as we can see with our esr60-based stable updates.

That's visible on different Linux systems at least.
