The browser console errors aren't part of the game, but being reported by the godot wasm export, they're not fatal and while they'd make debugging difficult, the fact this *is* a wasm export means debugging is a bit of a lost cause to begin with!
That may be true, but things like a blocking main thread can also be solved in a Godot export. Not all the errors messages are likely bugs though, I agree. However, the unreadable font is something that is fatal.
