But webkit loses the function sometimes for strange reasons. See testcase, it should just continue counting and counting, this does work in Firefox and Opera 63243 1 17701 sjoerdmulder 2007-12-04 07:18:46 -0800 Created attachment 17701 Testcase 63333 2 ap 2007-12-05 06:09:53 -0800 Confirmed with r28024.

One fix would be to mark all DOM objects held in the DOM cache which have custom data set on them. We would need some way to purge the DOM cache when the page it torn down (but we might do that already). I wonder how we keep custom prototypes alive... maybe we walk the prototype chain of any object when marking. 72776 10 mjs 2008-03-04 22:38:21 -0800 This issue isn't quite the same as Acid3 tests 26 and 27, but I have a fix that addresses both. (Acid3 doesn't rely on custom properties on the node). 72777 11 19543 mjs 2008-03-04 22:41:49 -0800 Created attachment 19543 patch v1 72778 12 19543 sam 2008-03-04 22:53:47 -0800 Comment on attachment 19543 patch v1 r=me.
