Problem with oracle join competition

I use pycharm 2017.3 eap version, but i think, that my question relates to datagrip and this issue (https://youtrack.jetbrains.com/issue/DBE-1140)

I write this code

SELECT *
    FROM SI_SUBJ_ACCOUNTS a
        INNER JOIN SI_SUBSCRIPTIONS S ON 
WHERE a.VC_ACCOUNT='111111' 

Competition after ON suggest me

This is not correct because i have alias for table si_subj_accounts a, not "a".

In stable version all works good.
