However, this should happen only when the region is valid. If the region is invalid, part of a region chain, positionForPoint should behave as usual for a block, otherwise it may run into an infinite loop, which eventually leads to a crash. 962215 1 219840 mihnea 2013-12-20 23:41:54 -0800 Created attachment 219840 Patch 962337 2 219840 kling 2013-12-22 09:45:05 -0800 Comment on attachment 219840 Patch r=me 962341 3 219840 commit-queue 2013-12-22 10:12:18 -0800 Comment on attachment 219840 Patch Clearing flags on attachment: 219840 Committed r160979: <http://trac.webkit.org/changeset/160979> 962342 4 commit-queue 2013-12-22 10:12:20 -0800 All reviewed patches have been landed.
