Merge https://chromium.googlesource.com/chromium/blink/+/d5088d76fcf75eaf23e30be43ebf119b2343dfed unicode-bidi: plaintext never worked properly when there is a line wrapping in a span with unicode-bidi: plaintext. The problem happens because constructBidiRunsForSegment does not have enough logic to understand the difference between line wrapping vs line breaking, the current patch just adds the necessary logic(e.g when a text has a line wrapping it needs to determine the directionality of the paragraph from the beginning of the isolatedInline)
I took test case from the patch: Link (removed -webkit-) - https://jsfiddle.net/q8m3o1tu/show Link (not removed -webkit-) - https://jsfiddle.net/t9r2s41n/1/show All browsers (Chrome Canary 108, Firefox Nightly 107 and Safari 16) render all boxes same with the same direction of arrows and stuff (no wrapping problem). Do we need this anymore? Thanks!
