tinyify makes bundle break

I'm using browserify on a project one of whose outputs is a webextension. When using browserify alone, the webextension works fine. When using tinyify, loading the extension fails with "Uncaught ReferenceError: require is not defined".

I have verified that I am using the browserify output in both cases. The only difference is using tinyify or not.

The report names no repository files or tests. Start by reproducing the browserify and tinyify webextension builds, then inspect the generated bundle around the unresolved require reference; done means the tinyify output loads without the reported ReferenceError and the regression is covered by a test.
