Describe the bug
To remove multiple controls from dynamic FormGroup not working with removeAt. My case i want to remove multiple FormControls from FormGroup then need to push new multiple FormControls in the same FormGroup. At that time removeAt will not worked.

If i loop through my FormGroup & try to use removeAt it will execute only one time then break the loop, also i have other logic codes below that also not executable.
