What
A plugin served in place from its source directory (link mode, no cache copy) is not loaded if that directory contains the current working directory, because its files could not be protected from sandboxed commands running there. The reason appears as a plugin load error.
Evidence
which contains the working directory, so its content could not be protected from sandboxed commands here.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
