      Changed Assigned To from “Bogdan B.” to “Kevin B.”

      Changed Status to “Confirmed”

      Changed Title from “Transitioning Left of absolute positioned elements within inline element” to “Common transition from percent value to unitless value jumps through 100%”

    • At least I would expect that animating for example “25%” to “0” should have the same animation in result as if animating to "0%". However Edge appends a “px” to 0, even though according to “After a zero length, the unit identifier is optional.”

      Thank you for working on Edge :)
