 > Do we have a good test making sure the WASM part is actually working as
 expected?

 I found some "test": On mobile I get a warning now due to an unresponsive
 WASM script. That's pretty bad because users can start surfing while
 HTTPS-E is not ready yet and it gets our fundraising banner in a weird
 shape (not everything is positioned correctly). I am afraid we can't ship
 this as-is.

 Interestingly, though, we *do have* WASM enabled on the standard level in
 our alpha and nightly builds and I don't have that issue on that level on
 that device. Thus, the problem here is not wasm-on-android per se.
