Node tree not fitting and can not pan to correct it

I just look in to a job and it has many nodes. After clean up node graph nodes are placed on greed so to say but half of them are off from node area and i can not zoom out or pan to hidden nodes at all. This is the problem R14 already had but now it seems to be inherited to R15 as well.

Could this be addressed please?

This always comes up with VFX heavy or beauty work for me.
