Steps to reproduce:

1. Login WhatsApp Web, open a new tab, load http://web.whatsapp.com, click Back button, the button will not work.

Actual results:

The Back button does not work.

Expected results:

The button should work.

I managed to reproduce the issue on Windows 10 x64 but from what I noticed the same thing is happening also on other browsers, this behavior could be intended.
I'm going to assign "Tabbed Browser" component for it.

Hi Dão,

Here it is: https://bugs.chromium.org/p/chromium/issues/detail?id=976474

The attack scenario is: attackers send this kind of URL to make the desktop browsers of victims use not work as normal.

I can't reproduce this, feel free to reopen if you can.
