I have not found any mentions of this so I wonder if it is a local issue, but since it is not realizable, it is hard to replicate in incognito or with extensions turned off. But it’s also only happening on my bubble app (live and staging) so I’m not sure.

Reloading again always clears it.
You can see that it is also in the debug panel.
