Bug 1528828 [wpt PR 15449] - [css-tables] Add some subpixel collapsed border tests, a=testonly Automatic update from web-platform-tests [css-tables] Add some subpixel collapsed border tests This CL contains tests only, no behavior change. Chrome passes only 001, no matter the device pixels. Safari-lodpi and Firefox-lodpi pass only 001 and 002. EdgeHTML 18.17763-lodpi, Firefox-hidpi, and Safari-hidpi pass 001, 002, and 003. From a plain reading of the tables spec the 003 test is correct. But given its rampant failure (only EdgeHTML passes when 1x device pixel per CSS pixel), it'd be reasonable to codify the current empirical behavior somewhere, if it's not already in a place that I missed. Chrome probably passes 001 but fails 002 because of LayoutUnit's 1/64 pixel precision but that's not confirmed. Note that these tests will become invalid if the proposal in https://github.com/w3c/csswg-drafts/issues/606 is adopted.

<!DOCTYPE html>
table {
  border: 5px solid green;
  border-collapse: collapse;

td {
  width: 50px;
  height: 50px;
  border: 1px solid red;

<p>There should be a square with a green border, not a red border.
