Can't have multiple Choice tags with both required and perRegion attributes set to true

**Describe the bug**
On creating an xml, with multiple Choice tags (I tried it with TextArea as well and it made the same behavior) where both tags have `required=true` and `perRegion=true`, only one of them is set to be required while the other one is get by-passed.

This is an example of XML I'm using

**Expected behavior**
While choosing only one choice and neglecting the other one and trying to submit, it should block me as both are required.
