refactor(forms): Add a test that uses ControlConfig with a non-static validator. (#49693)

dylhunn · dylhunn · commit 136ffbca8e9b · 2023-04-05T09:08:39.000-07:00
Previously, this PR cleaned up a bug introduced by #48679. However, since that PR needed to be rolled back, this PR now just checks in the test, to prevent that issue from re-occurring in the future. PR Close #49693
