1. Make your window small (e.g. 800x600 or smaller). 2. Load https://docs.google.com/a/google.com/document/d/1I3RfUbuVVoMB4JY3o6qypiEUv7Y7zfEGmG3V78Fa5Ok/edit. Initially it loads fine, then a few seconds after load, all the text resizes smaller, but the red underlines for spelling mistakes don't move. I bisected webkit revisions to http://trac.webkit.org/changeset/127438. I was testing on Chromium Linux.
Repro'd on applemac WebKit. Taking.
Looks like something goes wrong with sharing of ElementAttributeData for elements with inline style. I don't fully understand the problem yet, will continue investigating tomorrow.
