I have been very successful in replacing a JS browser application with Rust. It has been great, because Rust is much easier to change, and since the application is complex, I need to change it a lot.
But I wouldn't recommend it in general, because JS (and for slightly more complex things, TS) is much easier to create because of all the old Rust features that surface every time you mention it. And most GUI code is simple enough that you only have to write once, maybe fix a few details, and forget about it.
Wasm would be much more compelling if it was target by higher level languages.
