146907 2015-07-13 11:22:41 -0700 Arabic text does not shape properly when split into <span>'s 2015-07-13 13:51:01 -0700 1 1 1 Unclassified WebKit Text 528+ (Nightly build) Unspecified Unspecified RESOLVED DUPLICATE 6148 InRadar P2 Normal --- 1 sabouhallawa webkit-unassigned mmaxfield sam simon.fraser webkit-bug-importer oldest_to_newest 1109145 0 256707 sabouhallawa 2015-07-13 11:22:41 -0700 Created attachment 256707 test case Open the attached test case and compare the first and the second paragraphs. Result: The second paragraph is shaped in two different passes as if they are separate runs. So the last character of the first run has a "final" shape and the first character of the second run has an "initial" shape. This bug is similar to https://bugs.webkit.org/show_bug.cgi?id=6148 but this one is way more important. It hits millions of Facebook users very often when part of the text is hidden and its visibility is controlled by "See more..." link. Once the link is clicked, the other span is visible and the bug is reproducible. NOTE: It is reproducible in Chrome bug fixed in FireFox. 1109155 1 webkit-bug-importer 2015-07-13 11:52:21 -0700 <rdar://problem/21797428> 1109200 2 mmaxfield 2015-07-13 13:51:01 -0700 *** This bug has been marked as a duplicate of bug 6148 *** 256707 2015-07-13 11:22:41 -0700 2015-07-13 11:22:41 -0700 test case test145.html text/html 92 sabouhallawa PHA+JiMxNTc1OyYjMTYwNDsmIzE2MDQ7JiMxNjA3Ozwvc3Bhbj48L3A+CjxwPiYjMTU3NTsmIzE2 MDQ7PHNwYW4+JiMxNjA0OyYjMTYwNzs8L3NwYW4+PC9wPgo=
