multi takes - solo lane [s] not "sticky" when track not selected

I am working with instrument tracks (midi data), recording many takes as lanes.
No problems with that, it works ok with each take recorded automatically in a new lane.

The annoyance is when listening to particular take, select it, choose [s] for solo, perfect, but once you select something else the [s] solo lane is lost automatically !
This is very annoying as one needs to change other parameters or track during playback…

Any idea ? or is it a by design miss ?

adding a video to make it clear…
Obviously, when there are many lanes already recorded, if I touch somewhere on the screen, they start to play all together !!!
Very strange behavior !
