Steps to reproduce: 1. Load a web page. 2. Type "about:blank" into the address bar and press enter. Expected results: Tab thumbnail shows the blank page. Actual results: Tab thumbnail still shows the page from step 1. This happens because we purposely ignore "about:blank" loads in the thumbnail update code.
