dashboard: cannot manually type custom check for row permissions

[dbm03]

When editing permissions for a table, if you manually type a "where" custom check in row permissions, it doesn't get parsed

To Reproduce
Steps to reproduce the behavior:

1. Go to Database
2. On a table (e.g. todos), click Edit permissions
3. Select a DML action for a role, e.g. Select for the user role
4. In row select permissions, select With custom check
5. Inside the where field, type the full name of a table.column, e.g. todos.id

Expected behavior
table.column input should get parsed correctly, same way as when you click on an autocomplete suggestion

Screenshots

Should instead show:
