  <!-- Detect severe performance and memory issues when large amounts of errors
       are reported from CSS embedded in a file with a long data URI. Addressed
       by 786108 for issues internal to the style system and by 796179 for issues
       related to the error console. This error console test should finish quickly
       with those patches and run for a very long time or OOM otherwise. -->
