Latest Node Group - possible UI bug?

Could somebody second that:

r55769, r55834

Node Editor -> Properties -> Interface
- Vertical Group Input/Output slider stubbornly returns to the default upper position when slided down.
- While sliders are separate for Input/Output, they work on not ‘own’ box if selection is not present in it.
- highlight in the actual Input/Output box of the in Properties selected Input/Output would help.

I can confirm that r55850.

The current workaround is to slide one of the input entries down a spot, but I have confirmed the bug here as well, so it really should be reported.

Thanks for confirmations, all. Reported as 34910.
