Sortable broken in absolutely positioned div with bottom 0 when using jQuery 1.8+

[gabaum10]

I am seeing some strange behavior with Jquery 1.8 with Jquery UI 1.8.23 where scrolling is not working on a sortable list. Here is a fiddle example:

As you can see, the list is not scrolling on the drag. If you downgrade to 1.7.2, everything works as desired.

Here is a StackOverflow question that another user opened about this very issue:

The demo pages, such as ​http://jqueryui.com/demos/sortable/#delay-start don't scroll either.

I wouldn't say this issue is that minor. If you've got drop areas only accessible after scrolling, it breaks functionality.

I agree with Andri. I have exactly that situation where the droppable is generally going to be off the screen and therefore this part of my application is completely unusable.

The priority doesn't really change anything. Feel free to submit a pull request if you'd like to see this resolved sooner.

Fair enough. :)

Turns out this is an issue with the argument list change to $.css() in jQuery 1.8. Looks like you removed the instances of $.curCSS() in master, but for 1.8, without knowing the code as well as you do, I thought it would be safer to redefine $.curCSS() as a function that remaps the arguments.

@dmaz99 Can you confirm whether this is working for you with 1.9.0?

Just tested and it works. Sorry I missed that 1.9.0 was released yesterday. We'll make due with this patch for our next release, but we'll take a look at moving to 1.9 soon.

Thanks for your help.

Thanks for confirming. I'm going to just close this as fixed in 1.9.0 then and not worry about fixing 1-8-stable. It seems like anyone using jQuery 1.8+ should be able to easily upgrade to jQuery UI 1.9.x.
