In Django 4.2, `process_lhs()` is called for IsNull lookups, which is how this bug came to appear. It was already there and could be reproduced on Django 3.2. The issue is when `LocalizedRef` is combined with a localized lookup. The lookup is unaware of the existing localized ref and adds another transform on top. This results in the expression becoming: ``` field->'en'->'en' ```
