Turns out Internet Explorer is even worse than imagined. It's right at the bottom of the Uncanny Valley--close enough to a real browser to make it look like it works, but lots of near-impossible-to-track-down bugs that make life miserable. Turns out that Node.normalize is broken (see the bug reports and a workaround), so I had to add a test in bililiteRange to check for that, and not bother normalizing text if it's broken. Normalization just means merging adjacent text nodes, so losing it makes things less efficient but it should still work. I'm not going to lose sleep over Internet Explorer's inefficiencies.
