User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20160512103502 Steps to reproduce: 1. Have <div> with "position: fixed" 2. Hide the element by rotating 90 degrees in Y axis 3. Show the element using "transition: transform 2s;" See: https://jsfiddle.net/b0st38uv/4/ or attached file. It behaves the same even in the current nightly (50.0a1). Actual results: The rotating element is not visible during the "show" animation Expected results: The element should be visible during the "show" animation.
