digitalmars.D.ldc - LDC to WASM failed?

I tried to compile the program as written in the article
https://wiki.dlang.org/Generating_WebAssembly_with_LDC
first sample add (not callback).

compilation is ok, I've got wasm.wasm that looks in binary like 
this
https://pastebin.com/JBr7V6if

but browser console says:
request sent wasm.html:20:7
response received wasm.html:8:9
instantiated wasm.html:12:11
TypeError: exports.add is not a function[Learn More] 
wasm.html:15:21

well, in binary representation wasm.wasm I dont see any text 
"add" (IMO method name should exists in any case when JS wants 
call it)

my current LDC version is 1.16.0.beta1

2nd question:
I understand that I cant import anything from Phobos yet, isnt it?
does LDC will give some wasm runtime in future?

There was a breaking change with LLD 8, requiring to use 
`-L--export-dynamic` in the LDC command-line. Is/will be fixed:

You can, if it's templates only without any dependency on C 
runtime and non-templated druntime+Phobos. See the touched test 
in the PR above for an example.

The compiler won't, but the community might; you're not the only 
one interested in some form of baremetal libraries, e.g., see 
https://forum.dlang.org/thread/szfzoaoizbgjzfpckmze forum.dlang.org.
