Slider handles overlap datepicker popup

[manfer]

When placing a datepicker in popup mode above sliders, the slider handles appear in front of the popup.

I have tried the solution ​http://dev.jqueryui.com/ticket/4456 but it does not work. Though I set the css:

.ui-datepicker { z-index:100; }

as soon as the datepicker pop-ups it is given again a z-index=1.

confirmed. This is due to: ​https://github.com/jquery/jquery-ui/blob/5bd5ef15f9f7d1820334abd52aa5ee4b25c992ba/ui/jquery.ui.datepicker.js#L693 which manually sets the zIndex of the datepicker div to 1 greater than the input it's spawned off of. If zIndex is already set by CSS, perhaps it should respect that instead?
