jQuery 1.4.3+ causes large resizable lists to hang in IE7

Reported by: anonymous Owned by:

Component: unfiled Version: 1.4.3

Blocked by: Blocking:

Using Resizable from jQuery UI, but the behavior changed in the jQuery core between 1.4.2 and 1.4.3, so it looks like a Core issue exposed by Resizable. Specifically it looks like querySelectAll() isn't ready for prime time in IE7. and both seem related, but have been closed without addressing the underlying issue. This is a serious regression, and makes 1.4.3 and above totally unusable. demonstrates the bug.

In testing earlier 1.4.x versions, it seems that they all have this performance regression, it's just a bit harder to trigger in 1.4 and 1.4.2.

The NodeSelector API wasn't implemented until IE8, so that likely isn't an issue. Furthermore, this isn't the bug tracker for jQuery UI-- is probably a better place for this to be triaged.

While a particular component of jQuery UI exposes the bug, the fact that 1.3.2 Core does not have this issue and 1.4+ Core does would seem to implicate Core.

In case anyone with the same issue stumbles across this bug report, the workaround of preventing mousedown from bubbling described in the below jQuery UI tracker worked for me:
