Progress Bar Doesn't Seem to calculate Group Nodes correctly (>100%)

### Expected Behavior

It looks like nodes being completed within a "group node" cause the progress bar to be calculated incorrectly. It should never show >100%.

### Actual Behavior


I think it is counting completed nodes within a group node, like 10/1 nodes done.

### Steps to Reproduce

Make a bunch of group nodes with a few nodes inside, then run the workflow.

### Debug Logs

```powershell
No logs are generated from the top-level progress bar that I am aware of.
