While I don't know for sure, this does very much feel like intended behavior. So I'd probably say this is a feature request/suggestion?
I agree with others, though. This does get quite annoying when planning nodes, switching back to craft view, starting a burn, and then switching back to map to view the trajectory. This will become more of an issue with staging. During burns, I prefer the map view, but when staging, I like to switch back to craft view to make sure staging happens properly.
If this is intended and here to stay as default behavior, perhaps a setting to disable this behavior would be nice.
