Attached is the html and other files needed to reproduce the problem in the browser example. This can be reproduced by scrolling the main text area to the end and then starting a selection from the bottom, continually moving the mouse up and down in the text area will eventually cause it to crash with a bad allocation. Unfortunately I was unable to pinpoint the crash or get a stack trace because Visual Studio would struggle to give one and ultimately crash as well.
