Description
Major browsers have implemented position:sticky for table headers in a way only cell are sticky, not collapsed borders, see https://jsfiddle.net/70vjwymx/ (header borders are transparent). I am not sure what should be fixed:
- my css (some additional settings)
- browser code
- specification
I suppose position:sticky was implemented to ease styling cases like sticky table headers so I believe borders should be a part of that sticky content.
