Alias in a view on a table with virtual column avoid index creation

This sequence has a failure on CREATE INDEX (Unknown column '.`r`.`DELETED`' in 'GENERATED ALWAYS')

CREATE TABLE `RULE` (

   `DELETED` BIT(1),

   `UNIQ_CODE` VARCHAR(255) GENERATED ALWAYS AS (CASE DELETED WHEN 0 THEN 1 end) PERSISTENT

);

CREATE OR REPLACE VIEW `V_RULE` AS SELECT DELETED FROM RULE r;

CREATE INDEX `RULE_IDX01` ON `RULE` (DELETED);

If I remove the alias ('r') in the view, everything works well.
Both scenarios works well in 10.5.9

I can't find in MariaDB 10.5.10 release notes what could cause this issue.
