Description Matt Lilek 2008-02-01 09:40:58 PST
After Adam's reworking of the node highlight code yesterday, the highlight no longer updates on Windows when switching dom nodes until the inspected window is focused.  Also, while docked, the node highlights can disappear completely at times.

For example:
1. Load the testcase in the URL and inspect the Top div - the highlight is correct.
2. Switch to the Bottom div - the hole for the Top div is gone and the entire webview is faded grey.
3. Click in the inspected window - the hole for the Bottom div appears.
4. Dock the inspector.
5. Walk the DOM from <html> down and notice the different highlight behaviors, especially how toggling back and forth between the Top and Bottom divs never causes a hole to appear.

I think the problem is that we translate the context before scrolling the element into view, which could change how much we need to translate by.

+    context.translate(-overlayRect.x(), -overlayRect.y());

Should we use save/restore instead?

I think it would be "in addition to" rather than "instead". I think we could save/restore in case the InspectorClient wanted to do more drawing of its own, but since the hope is that all drawing will go through this method I don't think it's really necessary.
