However, Chrome and Edge implements what I think is the expected behavior, according to the CSS Text 3 specification: https://drafts.csswg.org/css-text-3/#line-break-details "Except where explicitly defined otherwise (e.g. for line-break: anywhere or overflow-wrap: anywhere) line breaking behavior defined for the WJ, ZW, GL, and ZWJ line-breaking classes in [UAX14] must be honored. " 1735097 4 jameela.huq 2021-03-02 16:03:42 -0800 In relation to this issue, Chrome and Firefox both break on Japanese periods and commas when "keep-all" is applied: e.g. In the sentence "情報も、スキルも、つながりも。あなたの仕事と未来を支えるSNS。" Chrome and Safari will break here [、。] however, on Safari, it will not break at all, which is very frustrating because "keep-all" is one of the few, reliable ways I have to break Japanese sentences appropriately at the moment. 1831508 5 crzwdjk 2022-01-17 09:45:20 -0800 This has been fixed by r288070 allowing LFC integration to work with the complex text path. *** This bug has been marked as a duplicate of bug 235266 *** 368552 2019-04-30 05:44:18 -0700 2019-04-30 05:44:18 -0700 Test case to reproduce the issue line-break-anywhere-2.html text/html 172 jfernandez PCFET0NUWVBFIGh0bWw+CjxzdHlsZT4KZGl2IHsKICBmb250OiAyMHB4LzEgTW9ub3NwYWNlOwog IHdpZHRoOiA0Y2g7CgogIHdvcmQtYnJlYWs6IGJyZWFrLWFsbDsKCiAgYm9yZGVyOiAxcHggc29s aWQ7Cn0KPC9zdHlsZT4KPGRpdiBjbGFzcz0idGVzdCI+WFhYWCZuYnNwO1hYWFggWCBYPC9kaXY+ Cg== 368553 2019-04-30 05:47:55 -0700 2019-04-30 05:47:55 -0700 Actual result actual.png image/png 1052 jfernandez iVBORw0KGgoAAAANSUhEUgAAAD0AAABdCAYAAAAWlm6zAAAABmJLR0QA/wD/AP+gvaeTAAAACXBI WXMAAAsTAAALEwEAmpwYAAAAB3RJTUUH4wQeDC8dYULoMAAAAB1pVFh0Q29tbWVudAAAAAAAQ3Jl YXRlZCB3aXRoIEdJTVBkLmUHAAADgElEQVR42u2c30tTYRjHv/PHhhEEZlT+iFIIJgbVTVDQjSG0 uUxMLNa0FH+Aij/+kBg5f6QYGWplJQtzhkHYTT+hCy2G1mo1Ckoky6i5OdeNF4Vu9b477nnP8X0u z3nOAx/O8z7nfT8XR/f923wYGywSsAFDQktoDUfSWhdN5kJNwLlG7/4/dLQH1BLRXpxc0xJ66R36 64tgMp9Hx+Ti6vsBNy5VW2Cy1KLXHRAvnws6aQ/KmkqQlTALV8c1vFn682YInqF2jHzSIfNkM2xG vXj5vO2dvPc0mk5kIOxzwuH0YXnl+vLHO2i75QUyLGg5a4Re0HzONa1HbnkjTNtDmBnsxL1ZAJiF yzGAmVA6ilsqYDSInM87yAx5qGwoQNriJPq6J+B90IUrk0FkFkVoI9Hyead3ysEq1OenYuGRA63t T+FPt6DFlhuxjUTL5/xkbcKhilMw6vzw+/U4Um77RxuJls8FHYTbOYbpMAAE8Gz0Pr6oKp8DOjA9 ALvTh8ScM2gtyUJg6irax+dUk88OHXyNfvswfNiF0uYyHLPWoiDtF55f7sTDeRXks0MHMTNox/AH IKu4EWXZSYBhP85VHcbmhSfo7nmMH0Lnc0AHPUOw336P8A4zGq1GJK9c33K0GrZ9Bnyd6ELvi5/C 5nPsvd/i+oWb8Ia24nhDOfL+mo7bYK4rRXbiHMYdfXi5KGA+D7Tnhh1D3iWk5tej8kDK6gd3l6Cu cCfCn8fQNvAK00Llu6NC69ZSwCZzoSYkQiQGeZ6W0BJaQktoYZ1aXKC14shYQyOOjDW04shYQyuO jDU04shYQxOOjDU04MhYQ/2OjPklq96Rsbe16h0ZM7LqHRnz3lsDjowtQoI5NenI5HlaQktoCb2R oBV0UiT1uaAVdFIk9XnbWyknRVWfc00r46To6vMOMgWcFGl93ukdq5Oirs/5yYrNSdHX54KOzUnR 1+eAjtVJUddnh1bASZHWZ4dWxknR1eeAVspJUdXn2Hsr56RI6vNAexidVHBdnRprfUhHJs/TElpC S2jpyOLhsOigCR0WaXtTOSziNU3jsOgHGYHDEmJ6x9thCfLJiq/DEgQ6vg5LCOh4Oyx6aAKHRQxN 47BIoakcFuHem85hkUFTOqz1jog/bMqxXsSINerOHHk1PXDVyPO0hFZde2vlR2xrhU7+QlNCS2gJ LaFVGL8BgAhOui00DlUAAAAASUVORK5CYII= 368554 2019-04-30 05:48:16 -0700 2019-04-30 05:48:16 -0700 Expected result expected.png image/png 1078 jfernandez iVBORw0KGgoAAAANSUhEUgAAAEAAAABgCAYAAACtxXToAAAABmJLR0QA/wD/AP+gvaeTAAAACXBI WXMAAAsTAAALEwEAmpwYAAAAB3RJTUUH4wQeDC4kJ1xReQAAAB1pVFh0Q29tbWVudAAAAAAAQ3Jl YXRlZCB3aXRoIEdJTVBkLmUHAAADmklEQVR42u3c3UtTcRgH8O9SJ0YQmFH5EqUQTAyqm6CgG0No c5mYWNi0FF9AxZc/JEbOlxQjQ62sZGFqGITd9ApdWDG0VispKJEso3RzrhsvCvPlhL/n+eme5/Ls 2eB8zzm/w/mw55i+f5sMIYxrA8K8JAAJIMwrcrkGqy1zXexof9+d/wtgqS+vlVrqIMoaIAGspGbf oaMiC1bbOTQOzyz83O/BxRI7rPYytHn86vvJA4jcjbzqHCRtGEd/41W8mf3zwyC83Q3o/WRC4oka OCxm9f0cl0DUnlOoPp6A0JgbLvcY5ua3z328jfqbPiDBjtozFpiJ+hnWADNSC6pg3RbEaFcT7o4D wDj6XZ0YDcYju7YQlmjKfo5FMDoNRZUZiJsZRnvLEHz3m3F5OIDErEVOTdX9HHeBmAPFqEiPxdRD F+oanmA63o5aR+qip6bqfobb4EYcLDwJi2ka09NmHC5wLHNqqu4nDyAAj3sAIyEA8ONp3z18Ye0n DsA/0gmnewwRKadRl5ME/4sraBicYOunDSDwGh3OHoxhJ3Jr8nA0vwwZcb/w7FITHkwy9NMGEMBo lxM9H4Ck7CrkJUcC0ftwtvgQNk09RkvrI/wg7ScOIODthvPWe4S221CVb0HU/PbNR0rg2BuNr0PN aHv+k6yf+FngLa6dvwFfcAuOVRYg7a9VeSts5blIjpjAoKsdL2cI+qkD8F53ots3i9j0ChTtj1n4 I7tyUJ65A6HPA6jvfIURpf0eBFYxANNyLG61Za4LEFlsH8QDJAAJQAKQAFbdBI0WoyGqMUGjxWiI ykzQaHEZokITNFo8hqjWBI0WgyEqN0HdzJHBBHUzR3IT1M0ciU1QN3OkNUHDB5/eEBWaoPFTn8MQ lZmg4d1nMkQ1Jmj4WYDPEBWYoFGzCyo2R4+YoJiggIgEIAFIAKQmqJshkpugbobIYYK6GSKDCepm iBwmqJshcpigbobIYIK6GSK5CepmiMQmqJsh0pqgboZIa4K6GSKxCepmiLQmqJsh0pqg6v/9BQ0b pZigmKCAiAQgAUgAlCa47gJgnO3V5hLgmu3VaA3gme3VaxFkmO3V7i5APdur4W2QdrZXwwBoZ3u1 C4B6tlevABhmezUKgGe2V5sAuGZ7NXkW4Jvt1SIAL+Nsr+pa0cvUUvIvoDd/yScFpJW2or9UPEAC WGu1oktgvbxU8V9lktfqyhogAUgAEoAEIAFIAOFavwEQ50/Bkmt8JQAAAABJRU5ErkJggg==
