Persistence traces get discarded after choosing channelHad the persistence running for a while, and had to change the channel for the right vertical scale (change, and not activate). All traces dissappeared.

The same behaviour happens in stop mode. And also if just the menu for a channel is opened by the channel widgets on the screen, when it was selected before already. WHY, just why?
What should i call this? Issue, bug or "wanted behaviour"? I understand that those traces cant be scaled or moved, and i did not do this...
The kind of same behaviour and what i consider even worse happes when adjusting time delay with a math average trace in
stop mode: Everything gone! It may take many minutes to get this data, and then its gone in an instant.
