dlopen doesn't work with -sWASMFS=1

main.c
`#include
#include
#include

int main() {
void* handle = dlopen("side.wasm", RTLD_NOW);
if (!handle) {
printf("Failed to load library: %s\n", dlerror());
return 1;
}

void (*symbol)();
symbol = dlsym(handle, "print_hello");
if (!symbol) {
printf("Failed to load symbol: %s\n", dlerror());
return 1;
}

symbol();
dlclose(handle);
return 0;
}
`

side.c
`
#include

void print_hello() {
puts("print_hello() has been called");
}
`

expected output: "print_hello() has been called"
real output:
"Failed to load library: Could not load dynamic lib: side.wasm"
"Error: http://localhost:8002/side.wasm: file not found, and synchronous loading of external files is not available"

If I remove "-sWASMFS=1" flag from the build command - everything is OK.

build commands:
emcc side.c -o side.wasm -s SIDE_MODULE
emcc main.c -o main.html -s MAIN_MODULE --preload-file side.wasm -sWASMFS=1

emcc -v
