Text fields often flicker when their value is set with javascript. That is, when their value is changed, the field is cleared to white for a split second, then the actual value is drawn.

Created attachment 13704 [details] Change -[WebCoreFrameBridge needsLayout] to consider pending subtree layout The flickering was caused by painting without updating layout first, as a result of -[WebCoreFrameBridge needsLayout] returning NO because the required layout was for a subtree only.
