Your if statement seems to be inverted.
Seems more sensible to skip if cloneable entities are empty or if target entity is not present in the array.

Let's wait for pipeline to run, once green will merge and release.

In its current form this will return false if the target_type is in the cloneable_entities config. This is the opposite of what you would want in a isClonable function.

I believe Willempje2 is right, updated the MR to correct the condition in the isClonable() function.
Also attaching a patch here.
