Bug 1496274 [wpt PR 13345] - [LayoutNG] Correct clip-path reference box calculation., a=testonly Automatic update from web-platform-tests[LayoutNG] Correct clip-path reference box calculation. We used coordinates relatively to the line box, while we were expected by the caller to be relative to the containing block. Flipping for writing mode was bogus for NG (but needed by legacy), since NG uses truly physical coordinates. Hardened tests to contain a leading line and padding, and leading content on the first line of the clipped child.
