Multi Group List fails

[thumDer]

Describe the bug
forms.SelectFromList fails with the following exception:

Traceback (most recent call last):
 File "C:\_stuffz\pyRevit\Extensions\pyNexTools.extension\pyNex.tab\Views.panel\PlansPerLevel.pushbutton\PlansPerLevel_script.py", line 60, in <module>

TypeError: Error in IEnumeratorOfTWrapper.Current. Could not cast: IronPython.NewTypes.System.Object#INotifyPropertyChanged_28$29 in System.String

To Reproduce
Just call the show function of SelectFromList in any script with a Dict as the context instead of a List to have a multi group list (as per https://www.notion.so/Effective-Input-ea95e95282a24ba9b154ef88f4f8d056)

Expected behavior
A nice multi group list shows up.

What object types are included in the dict?!

[thumDer]

I've tried with ViewPlan, string, even with the default example dict from notion. The same form works fine with a ViewPlan list.

Fixed and will be published with next release

Thanks! :)
