UX: 2 Fibery instances: RichText Editor: jumping cursor

I have two Fibery instances (web version under Windows 10, Chrome) opened on 2 monitors with RichText on each one of them - same entity, just different areas of the entity.

When I switch from one window to the other and click some part within the given text, cursor jumps suddenly to a completely different position within that text.

Feels very annoying and time consuming.

PS: It’s not easy to catch it though - not that easy to reproduce as I thought initially..
