Issue #14126 was closed as fixed but the problem which was addressed persists. Similarly, #15549 was tagged "expired" which suggests attempts to fix will no longer be made.<br>
<br>
But IMO both problems are definitely worth having another look at. So I wonder whether something can be done to have those two issues treated as regular ones again.<br>
