While trying out the new Safari extension support, I attempted to install Wipr 2. I used the install from file option and selected Wipr from my Applications folder. Installation completed without error, however only one part of the extension was installed.
This extension has five parts, and only Wipr Extra is being installed. A successful install in Safari looks like the following.
This is probably an edge case since it is the only extension I recall using that includes multiple components.
I expected all components to install in order to provide a functional blocker and Wipr's test utility to report success.
