Losing selection when clicking checkbox label

I am trying to get a checkbox with a label to function so that when you have text selected in a contenteditable div, clicking on the label will not lose the selection from the div. The label still needs to apply the standard checkbox tick/untick upon clicking it, but keep the focus & selection intack on the div.

Doing a simple focus() on the div won't help as the selection will be gone (and caret is at the beginning). I could of course look into a way for storing the selection object and trying to assign it b开发者_JAVA百科ack after the label click, but isn't there any simpler way of keeping the selection?

(the reason I need to do this with label & checkbox is because I will be using jQuery UI buttons and I will need the the toggle functionality of them)

On a similar note, if you click the checkbox, you usually still keep the selection in the div, but at least on FF4, if you press the checkbox very frequently (<1s), it will lose the selection. Any idea what's going on there? answered below

It's a Firefox bug marked 490367.

According to the bug description, double-click functionality on input fields will act unusually when there is a contenteditable div on the page.

I noticed the strange behavior while trying to replicate it manually so I guessed it was a bug. I don't know of any workarounds.
