SQL Lab horizontal resizer can be dragger past the bottom of the page

[john-bodley]

In SQL Lab one can drag the horizontal resizer off the bottom of the page and there's no way to re-drag the resizer back. One needs to reload the page in order for the resizer to be repositioned.

Expected results

One should not be able to drag the resizer past the bottom of the page.

Actual results

It seems in some circumstances the resizer can be dragged past the bottom of the page and thus not recovered.

Screenshots

How to reproduce the bug

1. Go to SQL Lab.
2. Drag the horizontal resizer past the bottom of the page (and release the mouse click).
3. Observe there is no way to drag the resizer back.
