Description

The attached test case provided by mleich rather easily reproduces an assertion failure related to the change buffer, on all server versions 10.6 through 10.11.

The involved code was refactored as part of ~~MDEV-27058~~, but it is yet unclear if this failure is a regression starting with 10.6.

The change buffer was disabled by default in ~~MDEV-27734~~, deprecated in ~~MDEV-27735~~, and i t is scheduled for removal in ~~MDEV-29694~~. With ~~MDEV-29694~~ present, the test will not crash.

The assertion fails with various stack traces, related to buffering purge operations (not inserts or delete-mark operations).
