> We should not update entire document on an attribute change. There are explicit and implicit arguments changes (setAttribute and say changing style via CSS OM). We detect first via instrumenting DOM mutation and we have special handling for the latter. What attribute of DOM changes and why in your case? I.e. what part of WebCore obsoletes the old value and computes the new one?

For example, when mobile is rotated, the width of <div> becomes more wide, but the "Metrics" and "highlight overlay" still show the old results (refer to the attached picture2 and picture3).
