Crossfader should control the total *time* of an AUTOMIX transition

When AUTOMIX is enabled, the crossfader should control the total *time* of a transition and move all other parameters (like EQ)

Use-case:
I have automix enabled (with a default crossfade duration of 32 bars and EQ transition). Touching the animated crossfader should accelerate/decelerate the whole transition and modify the EQ curves accordingly.
Instead, I get graphical clipping of the fader and cant touch it while it is animating
