Nodes with multiple reroute inputs don't execute if inside a group node

Specifically, I mean something like this:
If I turn 2 widgets into inputs on the KSampler, hook them up to reroutes and turn that into a group node, it will not execute.
1 is fine, after that it stops working. It doesn't seem to matter what the inputs are, though I've only tested for number types.

A workaround is to use a node that accepts that input and can return it unmodified as input into the group node:
(number type nodes with their value widgets turned into inputs)
