Related with this issue #358082: jQuery 1.3 in Drupal 6.x

To help ctools work with jQuery 1.3.2 in jQuery Update can we please remove the @ in the selectors. It was depreciated as of 1.2 and removed in 1.3. Change highlighted below.

jQuery 1.2.x:
$("a[@href*='admin/build/testing']").doSomething();

jQuery 1.2.6 and 1.3.x:
$("a[href*='admin/build/testing']").doSomething();
