We worked on rewriting the code to make it faster and the bug no longer
appears with this version.

Unfortunately, I am afraid it's a little bit late to include these
changes into the next release so the fix will probably appear only
in 3.9

In the meantime, the solution I proposed here:

is the best alternative.
