1405067 - Long running console input command breaks future input and prevents toolbox from being closed

Status: NEW

(DevTools :: Console, defect, P3)

Description

[Brian Grinstead [:bgrins]]

STR:

Open console
Paste this and press enter:
      var proxy = {};
      for (var i=0; i<100; ++i) proxy = new Proxy(proxy, proxy);
      proxy

Expected: Proxy gets logged
Actual: Input field regains focus before a response comes in at which point you can enter another command without getting a response, and if you attempt to close the toolbox then the toolbox UI gets destroyed but the console frame stays opened

I eventually see:

But we should try to at least make the frontend fail more gracefully if possible in this case.
