Big console in "Open web console" is stretched over the whole screen instead of keeping the correct side ratio

rc.4

Always

1. Go to the VM overview
2. Click "Open web console" 

The console takes the whole view, no matter the side ratio

For console, where the view is not responsible to the size of the screen, it should occupy the most place possible while maintaining the ratio of sides.

In case the VM is able to respond to the changes of the screen size, it should.
