Andrew Scott d543b13e5c Revert "fix(core): log error instead of warning for unknown properties and elements (#35798)" (#35845)
This reverts commit 00f3c58bb929d9afa10ab3c4f1b9ee7a0077ba57.
Rolling back because it could be breaking e2e tests that assert that
there are no errors in the console after the assertions have run. We can
re-add this in v10.
