Wasm blocks the input of <Input /> and <Textarea /> in html.

I'm using "emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 2.0.14".
After I loaded my wasm to the web page, all the and disabled. I couldn't input any character.

Also I tried to stop the key related listening by using

`emscripten_set_keypress_callback(0, 0, 0, 0);
emscripten_set_keydown_callback(0, 0, 0, 0);
emscripten_set_keyup_callback(0, 0, 0, 0);`

But it doesn't work. I got this error "SyntaxError: Failed to execute 'querySelector' on 'Document': '0' is not a valid selector.".

My wasm is about media rendering. And I'm using SDL.

Can anyone help on this?

Thanks
