[Hummingbird] Hoping for clarification on compression page

I’m confused. When it says it’s compressing, is it doing something or not?

I read the doc and I know we need to refresh the homepage to reset that, but even after a reset, that says compressing until (?) a shift-refresh is done on the browser. I think it would help to indicate on the minification page what’s expected.
