Comment 1 for bug 402160

The following patch to lazr-js shows more information about the error, and also makes things work again. Essentially, the error is caused when val is undefined, and it attempts to do style['height'] = undefined. I don't know why val should be undefined, nor do I know why that should really be a problem. Perhaps just doing val || null would be enough to work around this problem for now.
