When the admin bar is shown on the page, elements inside of it are visited by tag visitors in Optimization Detective. However, there seems to be very little to no benefit to visiting these elements. In the same way descendants of NOSCRIPT are omitted from processing (#1783), it would seem like DIV#wpadminbar should also be skipped. For example, when a tag visitor is tracking IMG tags, the first two elements appearing in URL Metrics for pages with a logged-in user would be:
