Description

Hi, @marko, it seems that the fixing for ~~MDEV-28689~~ is buggy. The lock thd->data_mutex is still not released during erroneously writing to the destination stream and writing to the destination stream (Line 246 and 256).

Due to the original issue is closed, thus I just open a new issue.
