[form] validation of grouped field shows multiple error messages

Bug Report

I noticed that after the 2.9.3 update, grouped fields show a repeating validation error for each field inside the group. This used to be 1 message before.

I tried using the new errorLimit: 1 setting, but that doesn't seem to work in this case.
