The following (untested) structure should be immune to this problem...use the knowledge as you see fit.
USING ('example_attribute_value' = ANY ( ARRAY( SELECT unnest(attr) FROM current_attributes() ca (attr) ) )
I cannot imagine the ARRAY(...) being removed and its presence should force the scalar = ANY(array) interpretation.
This does seem broken and likely to be back-patched though - and unnest+ARRAY is definitely inefficient so there is a trade-off involved - but hopefully only in the short-term (a couple of months probably...?).
