ui.position generates different position in static context

[AzaToth]

as seen in ​http://jsbin.com/itato4/14, if a span in a div has a call to position executed twice, it wont get the same position in the second call. In a loop it becomes a "wobbling" effect (unwanted often).

Visible in firefox, not visible in chrome.

You can do a bitwise equivalent of Math.floor(num) with num

Replying to paul.irish: You can do a bitwise equivalent of Math.floor(num) with ~~num

Fixed in ​9541bd0bf2ca72795e8f2b2c1d3accc32afcac96 using parseInt() which is what core does for pixel values.

Is there a reason why parseInt() was used rather than Math.round()? This choice can cause 1px offset issues in Firefox where decimal values >= .5 are concerned. See ​http://jsbin.com/uceje4/2
