Previously, the only tags in which `newline at` was supported were `{@code}` `{@literal}` and  `{@snippet}` ... and this tag predated `{@snippet}` which is the main reason it's not included here.

Now `newline at` is supported in all inline tags, so the scope of this check is broadened accordingly.
