Steps to reproduce: 1. Open http://output.jsbin.com/xedane/quiet in Safari on iOS 9.3.2. 2. Tap the "Launch modal" button. 3. Scroll down to "field 7". 4. Tap into the <input> below "field 7". 5. Tap into the <input> above it. Actual result: While focusing the <input>, the modal moves up and down multiple times, causing an unsightly jiggling/shaking/jerky effect Expected result: When focusing the <input>, the modal should move smoothly, preferably in a single motion.
