Created attachment 42656 [details] transformBug.tar.bz2 This is a modified version of the fancybrowser example that highlight the problem. This seems to only happen if we use jQuery to iterate and if we set the -webkit-transition and -webkit-transform properties in two different calls of evaluateJavaScript. If we don't use jQuery to iterate or if we do the two iterations in one call to evaluateJavaScript, the bug does not occur.

CSS transform and animation only works if the value is not "changed programmatically", which in practice means you have to enter the event loop once before two change of value. Isn't that the problem here?

This is an ancient bug, and deals with the side effects of evaluateJavaScript on animations, which is out of scope for anyone :) If someone feels strongly about this, please reopen.
