matteocontrini thanks for the extra check!
I don't remember experiencing this myself either.
If we can find a particular browser and set of steps to reproduce reliably, this would be very helpful!
There's always the risk an extension is playing a factor, in which case it might only happen under even more odd circumstances 😅 If anyone else is experiencing it on a different website, ideally our demo websites or here, that would be a good indication towards an actual issue with Flarum.
