Example HTML file that shows the problem

OVERVIEW:

This is a repeat of bug 75555, which was closed (automatically?) when the new Web Inspector appeared.

Any CSS data URI is counted twice against page weight: once for the CSS code, and once for the separate resource entry for the image or font represented by the data URI.

STEPS TO REPRODUCE:

Open Web Inspector, load a single HTML page that uses a data URI in a <style> element, and look at the Page Weight indicator.

EXPECTED RESULTS:

The Page Weight total shows the exact HTML file size.

ACTUAL RESULTS:

The Page Weight total shows the sum of the HTML file size, PLUS the size of the image or font represented by the data URI, since it gets a separate Resource entry

ADDITIONAL INFO:

You can see this in action at http://75thtrombone.com/links/webkit/page-weight-test.html . That page is also attached.
