kotlinlang

Trying to run kotlin-wasm-examples and it fails on Firefox 115.0.2 and Firefox Nightly 117.0a1 with this:

```GET<http://localhost:8080/favicon.ico[HTTP/1.1> 404 Not Found 0ms] 

Using experimental Kotlin/Wasm may require enabling experimental features in the target environment. - Chrome: enable WebAssembly Garbage Collection at <chrome://flags/#enable-webassembly-garbage-collection> or run the program with the --js-flags=--experimental-wasm-gc command line argument. - Firefox: enable javascript.options.wasm_function_references and javascript.options.wasm_gc at about:config. - Edge: run the program with the --js-flags=--experimental-wasm-gc command line argument. - Node.js: run the program with the --experimental-wasm-gc command line argument.

Uncaught CompileError: wasm validation error: at offset 525346: incompatible super type

With Chrome works just fine. All flags are true.

I checked this, and get exactly the same errors in Firefox 115.0.2, and everything works fine in Chrome.
