this feels wrong. Adding a runloop entry shouldn't be necessary

In that case I'm unsure how to resolve this. At least as a temp solution moving the set into the runloop allows to avoid getting the hard error You modified errors.model twice in a single render from #438 and is also the often-mentioned solution from the original discussion of the Glimmer 2 issue.

Interestingly, the error is only thrown on validation of existing records.

If needed, I can try to reproduce this in a Twiddle.
