Hi,
I have no idea on how to fix this. I've attached the test case to
reproduce it.
First execute the test SQL file, then select the last UPDATE query, and
hit F7. The graphical explain is kinda ugly because two nodes are one on
the other. That's not the first time I meet this bug. For example, when
you explain an DELETE query on a table with foreign keys.
If you know how to fix this, that would be great because I'm completely
lost here.
