Description
Spider does not load if the server is running with alter_algorithm=INSTANT (or NOCOPY, or INPLACE).
It is true both when the server is started with a non-default alter-algorithm and plugin-load-add=ha_spider or when they are set/loaded at runtime.
The failure started happening after these 2 commits in 10.10:

MDEV-27095 clean up spd_init_query.h
|
caused the error in the error log
ALGORITHM=INSTANT is not supported for this operation. Try ALGORITHM=COPY
|
but the plugin would still load (at least on startup).

and the plugin stopped loading.
