When tabs are loaded via AJAX the tab should display some kind of feedback that the tab is being loaded (throbber.gif or similar image).
To reproduce the problem: fill a namespace with many large images. When you load the namespace for the first time, the browser queue fills with processes waiting for the thumbnails to be generated. While the thumbnails ar still loading click an image. The third tab will stay white until the request can be processed by the browser.
