d() schedules another style recalc from inside style
recalc
Classification: Unclassified
Product: WebKit
Version: 528+ (Nightly build)
Hardware: Unspecified
OS: Unspecified
Status: NEW

This seems wrong. invalidateWhitespaceOnlyTextSiblingsAfterAttachIfNeeded() does a textSibling.setNeedsStyleRecalc(); in the middle of style recalc, which schedules the style recalc timer, even through we're in the middle of style recalc.
