Fail to find table alias to blend in SELECT + JOIN query

[panarch]

SELECT user.* FROM item LEFT JOIN user ON user.id = item.user_id;
SELECT * FROM item LEFT JOIN user ON user.id = item.user_id;

Above 2 queries work but,

SELECT Item.* FROM item LEFT JOIN user ON user.id = item.user_id;

This one fails.
[ERR] { "Blend": { "TableNotFound": "item" } }
Blend failed to find table alias.

[panarch]

SELECT item.*, user.*, u2.* FROM item
LEFT JOIN user ON user.id = item.user_id
LEFT JOIN user u2 ON u2.id = item.user_id;

Only u2.* is executed and both item.* and user.* fails with a same error.
[ERR] { "Blend": { "TableNotFound": "{table alias}" } }
