Summary Correct overflow propagation in BTT and RTL writing-modes

Consider merging https://chromium.googlesource.com/chromium/blink/+/5ffebc0f0a12542f4dd9824042904642528ad665 Overflow rectangles are not quite physical, not quite logical. This means that we cannot use clientBoxRect() directly to represent a rectangle that expresses exactly no overflow. This rectangle is the padding box (relative to the border box) in vertical-lr and horizontal-tb, but the block-direction borders need to be flipped in vertical-rl and horizontal-bt. fast/multicol/vertical-rl/rules-with-border-before.html now needs a rebaseline, because it now renders differently, but correctly.

I changed the test cases from Chromium patch: Test Case - overflow-btt-border-after.html - https://jsfiddle.net/k9e2qhz6/ (Remove -webkit- prefix) Test Case - overflow-rtl-border-after.html - https://jsfiddle.net/hcpjde3z/ Both show "PASS" for Safari 15.6.1, Chrome Canary 106 and Firefox Nightly 105. Is something else needed? Thanks!
