Reproduction steps:
1. Open project “Radio Button Group.zip”
2. Open “SampleScene”
3. Enter Play Mode
4. Observe Game view
Expected result: a “New button.” is displayed - RadioButtonGroup.contentContainer references the "unity-radio-button-group__container" element, so calling Clear() does not remove the entire group, and a new button is added
Actual result: nothing is displayed - contentContainer references the group itself, thus, the Clear() function removes the entire group including the label
