[WebGL] Failed to run player after building

[Kevin Mettes]

I build the bundles and pass it on to the build player. The build player is set to Auto Run Player, Connect with Profiler and Development Build.

After building I get the following exception

InvalidOperationException: Cannot process request because the process (11004) has exited.
