<pre>This was introduced a few weeks before the 12 branch cut, by
c3a21e5de3dc3f55e4d219afd55dec518159d356, and took some time to track down.
It was fixed, but the fixed added its own regression, so we should probably
cherrypick both:
- 6f0df3cddb3e3f38df1baa7aa4d743a74bb46688 (contains the regression testcase)
- 43cc4f15008f8c700497d3d2b7020bfd29f5750f
Alternatives would be:
- revert the original change
- cherrypick only the first and live with the relatively mild regression
--> Richard for a decision (I'm confident we need to do *something* for the
release)</pre>
