Subject: [PATCH] fix: broken download tests

Declaring `browserslist` in package.json exposed a bug in the
download.js tests that wasn't causing failures before (but arguably,
should): one can't use arrow functions to mock constructors because
calling `new` on them doesn't work.  See the NOTE under:
