Embedded WebExtensions are a bit weird, since they're kind of a hybrid of our legacy and modern add-on APIs, so I'd just bet on confusion. This is the only code that runs when the add-on is enabled: https://github.com/mozilla/addon-wr/blob/59659431fd2a75c33ac70a0e6e3e193a01ff8f66/addon/bootstrap.js https://github.com/mozilla/addon-wr/blob/59659431fd2a75c33ac... Lines 22 and 39 determine if the inner WebExtension starts up.
