I see how this is bad for performance. But I suspect that removing this call is
wrong for correctness. It's entirely possible that a script changes something
that triggers a style change and there is no other mechanism to guarantee the
style change happens.

We need to replace this mechanism with a better one, but just ripping this code
out is probably wrong. We'll need to construct a test case to demonstrate this.

I hope I'm wrong. I'm not saying review- because I'm not sure. Hyatt might know
better.
