jquery 1.4.3 multiple-selector on IE7 slow to a halt.

Reported by: godric Owned by:

Blocked by: Blocking:

Simple, using multiple-selector to fetch 400 elements on IE7,

but fine on firefox, chrome, safari.

jquery-1.4.2 = medium slow, but it will finish.

jquery-1.4.3 = won't finish, need to stop script manually.

Suspected to be related to the new browser-native-optimizations.

1.4.3 performs far worse than 1.4.2 on IE7, abnormally & unbearably worse,

maybe some unsuitable optimization got turned on by mistake on IE7?

Some more cross-referencing:

I guess it's the same bug as #7341, the multiple-selector might be using .add() internally.

Replying to [comment:2 godric]:

We are also stuck with 1.4.2 because of this checkSibling() IE problem. We have a page with 1.4.3+, UI 1.8.11, and a dialog with a large multiple select (hundreds of options). If you click on an option, IE 7/8 freezes in endless JS calls to checkSibling(). Please re-open 7341, many users will be stuck with 1.4.2 until it is fixed.

I think this bug can be closed too. I had lots of problems while selecting lots of elements with jQuery > 1.4.2, but using 1.6.1 (and 1.6.2) solves the issue.

In fact, I think it's faster now...
