High CPU usage when viewing certain pages #27

When I view https://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style with the Wikipedia guidelines ruleset loaded I see high CPU usage. It looks like the functions pollResize and scheduleRules are called frequently.

pollResize checks the height of the FiveUI report window every 100 ms, which causes a forced synchronous layout. As a result it takes ~195 ms to run that callback on my machine when viewing the Manual of Style.
