Parallel tasks can't be killed in Webstorm Terminal on Windows

This is admittedly Webstorm specific, but as FYI:

This is the same issue that I reported in Issue 32, but it occurs in Webstorm's terminal on Windows. Hitting Ctrl+C produces the prompt for "Terminate batch job (Y/N)?", but answering "Y" doesn't actually get you back a usable command line. It appears to be using the native Window command line behind the scenes since this is shown when I open the Webstorm terminal:

Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation. All rights reserved.

The result of hitting Ctrl+C: ^C^C^CTerminate batch job (Y/N)? Terminate batch job (Y/N)? ^CTerminate batch job (Y/N)? ^^CCTerminate batch job (Y/N)? Terminate batch job (Y/N)? Terminate batch job (Y/N)? ^CTerminate batch job (Y/N)? Terminate batch job (Y/N)? Y

It becomes frozen after answering Y.
