Big change for Chrome users, in my opinion. I use mouse button 4 and 5 for back/forward, but I do occasionally use Backspace as well.Description
Remove the default backspace event handler.
We have UseCounters showing that 0.04% of page views navigate back via the backspace button and 0.005% of page views are after a form interaction. The latter are often cases where the user loses data. Years of user complaints have been enough that we think it's the right choice to change this given the degree of pain users feel by losing their data and because every platform has another keyboard combination that navigates back.
We're doing this via a flag so that we can control this behavior should there be sufficient outcry.
