wasm2js example not working

[nklhtv]

Describe the Bug

After successfully compiling and running the wasm2js example in Chrome, theres an error message in the console, instead of the log from rust.
In this comment @alexcrichton says it should not work with --target web but in #1750 adds this flag to the build step. Maybe thats what causes the issue and should be changed again?

Related to #2428 #1743 #1750

Also, the View compiled example online link in the wasm2js readme is not working.

Steps to Reproduce

1. cd /examples/wasm2js
2. ./build.sh
3. open http://127.0.0.1:8080/

Expected Behavior

to log "Hello, World!" in the console

Actual Behavior

throws an error

Uncaught (in promise) CompileError: WebAssembly.instantiate(): expected magic word 00 61 73 6d, found 69 6d 70 6f @+0
