Dragging the resize bar downwards

[noinkling]

On an error page, when the console buffer exceeds the size of the frame, shrinking it with the resize bar anchors it to the line currently at the top of the frame, when it should really be anchored to the bottom.

This means that, for instance, if you fill the console buffer with a bunch of stuff (using methods usually works), drag the resize bar up to make the frame bigger, then drag it down again to its previous size, you'll be in a different position than you were before, without doing any scrolling. Basically the behavior is inconsistent between dragging up and dragging down. Occurs in Chrome, Firefox, and IE11.

There's some other bugs I noticed, but seeing as this is in beta and under active development, I assume those will be fixed in short order. However I thought this usability issue had the potential to be overlooked.
