Hi there,
May I just ask, what device was this occurring on for you? and the system version you are using on the device? 
Latest Mojave. Intel Macbook Pro. 2019 or something
Thank you for the additional information.
This may be a bug 
, we’ll investigate further!
Hi there,
A follow-up to the above, I consulted with a member of the development team for more information on this.
They mentioned that the panel is related to a specific document. If you change tab, you will need to re-open it if you had it detached
Sounds like pain, right?
