I wasn't able to reproduce bug#34655 myself (these things tend to be
rather flaky), but I've now reverted commit
3eb93c07f7a60ac9ce8a16f10c3afd5a3a31243a, and at least bug#31238 is
now consistently fixed (for me at least). Basil, can you check whether
you can still reproduce bug#34655 with the current master?
Thanks!
