I have the same issues as well, but the main concern was not the drop script. If I leave items in the database and try to uninstall the package, it returns an error.
The reason I think this is happening is because the APM runs apm_package_delete function before it runs the drop script. That means the error occured before the drop script is executed, that means it not the fault of the drop script. But if the drop script was executed before the apm_package_delete function then problem would be solve.
Does anyone has any suggestions to the problem?
