I am experiencing the same problem in 19.10 (eoan), with the default Gnome DE, so no Unity involved.
The icon disappears for some seconds from the tray, and at the same time the browser seems to forget some data, such as favicons and most visited sites. I also tried to describe the issue here: https://askubuntu.com/questions/1223484/snap-chromium-randomly-flushing- cache Tell me if you need more info on this.
