Dependent query cannot recognize expr in more than 1 nesting level

repro: https://dbfiddle.uk/1BpvGW2V

here is the same repro working for MySQL: https://dbfiddle.uk/wa8Kc48N
and for PostgreSQL: https://dbfiddle.uk/6Z-IfLMx

The failing query patten is important to be supported. In complex queries, it allows to deduplicate subqueries used later more than one without having to put them in the main select.

I would be grateful if it can be fixed.
