Description Shawn Walton 2018-08-27 11:15:37 PDT
When an element has the CSS attribute `position: -webkit-sticky` inside of a parent with `display: table-cell`, the child element does not behave like a sticky element. Changing the parent to be `display: block` or have `float: left` fixes this behavior. Here's a codepen to illustrate the issue: https://codepen.io/shawn-walton/pen/WgwPWm.

I've verified this bug on both the latest version of Safari (11.1.2 (13605.3.8)) and the latest Webkit dev build (r235378) on macOS 10.13.6. The bug does not exist in Chrome 68.0.3440.106 or Firefox 61.0.1.
