What error message do you get?
> You need latest Chrome with "Experimental WebAssembly" and "Experimental WebAssembly JavaScript Promise Integration (JSPI)" flags enabled!
Now I'm wondering whether the top message goes away once the flags are enabled?
Yes. I thought it won't be good if it would download 3.5gb once you open the page.

No, I haven't added any checks for that (and I'm not sure how the first one can be properly checked), so it's just an info bar. Which is, eventually, misleading.
