It's possible for the style recalc timer to get scheduled after the layout timer (both delay 0). The layout timer fires first, so we do layout, but then the style recalc timer fires and we do style recalc and layout again.

This happens in fast/canvas/webgl/arraybuffer-transfer-of-control.html and likely other content.
