Bug 35816

Created attachment 50135 [details] The bugging Overview When you create a CSS transition using -webkit-transition-property and -webkit-transition-duration to animate the width or the height of an image (or their min/max variants) from a fixed size to the auto value, the animation will go towards 0px and then warp to the necessary size instead of going directly to the necessary size. Steps to reproduce: Run the attached file and mouse over the huge title. Optionally, read the comments that have been left there. Acutal results The animation animates towards 0px and then jumps to the automatic size. Expected results The animation should animate towards the automatic size.
