Add failing large HTML file test.

*This is essentially a trumpet version of the underlying issue in html-select: substack/html-select#10*

Running this test yields a bunch of `(node) warning: Recursive process.nextTick detected. This will break in the next version of node. Please use setImmediate for recursive deferral.` warnings, and then a stack overflow.

(Node v. 0.10.31)
