Can't click output window

[choccymalk]

When I click the output window, execution stops. This only happens when using packager.py. I followed the compilation instructions given, and used the latest emscripten version. I compiled it on Ubuntu 22.04 LTS.

dosbox.js:1 Uncaught DOMException: Failed to execute 'querySelector' on 'Document': '0' is not a valid selector.

This is due to emscripten-ports/SDL2#99, a simple fix is to add -s DISABLE_DEPRECATED_FIND_EVENT_TARGET_BEHAVIOR=0 to src/Makefile.am dosbox_LDFLAGS.

My fork has this fix: https://github.com/hpvb/em-dosbox
