wasm shared library preload-plugin loading just preloads, need to doc that people must load the lib later (and loadDynamicLibrary must look in preloaded libs) #7220
Description
ref : #6663
i have a function in a side module which i call during Module['onRuntimeInitialized'] called FOO which is exported from my side module using EMSCRIPTEN_KEEPALIVE
i used to be able to call Module ["_FOO" ](), I seems that after this PR i am not longer able to find this function.
i found that while using --use-preload-plugins, handle was calling Module['loadWebAssemblyModule'] directly, but the code to import the symbols into the Module object was in loadDynamicLibrary, so we can never find the functions exported in the side modules
