Parameter feature mandatory is ignored when the feature also has a group

Whenever you create a group for parameters that are bound to the same feature, and the feature is mandatory, the group overrides the mandatory property and, all of a sudden, the radio button is no longer present and you have to fill all the parameters bound to the feature to be able to submit the macro.

Steps to reproduce:
1. Create a macro
2. Add 2 parameters bound them to the same feature and mark parameter feature mandatory as true for both
3. Add the parameters to the same group
4. Use the macro

Expected behavior:
The macro parameter modals shows the UI with the radio buttons where you have to select only one of the parameters bound to the same feature.

Actual behavior:
The macro parameter modals doesn't show the radio button and requires you to fill in both parameters even if you should complete only one.
