Bug 246495

Created attachment 462973 [details] Screen recording - table tr border issue When a table tr element has a border applied to it with CSS, the size and placement of that row and its border does not render correctly (see the attached screen recording for a visual). It seems that including elements such a button in the table causes the issue, as tables without those elements do not have the issue. Demo page: https://codepen.io/dsenneff/pen/vYjbQYm/91d48ea673dcb4fd7c09e43be2b83384 Demo page (without CodePen wrapper): https://cdpn.io/pen/debug/vYjbQYm/91d48ea673dcb4fd7c09e43be2b83384 To replicate: 1. Load the demo page linked above. 2. Observe the top-border of several rows in the first table have rendering issues. The second table does not have any issues. 3. Using the browser inspector, toggle off-and-on the top-border style. 4. Observe how the table renders different as the top-border is turned on-and-off.
