Preedit and completed composition data is processed during keypress events. Thus, in this test, the unused data was still lingering during the next keydown event. The attached patch handles this situation by first clearing the previous data, if any exists during keydown events. 152983 5 40769 xan.lopez 2009-10-07 01:12:20 -0700 Comment on attachment 40769 Fix for this issue r=me 152987 6 40769 commit-queue 2009-10-07 01:23:40 -0700 Comment on attachment 40769 Fix for this issue Clearing flags on attachment: 40769 Committed r49233: <http://trac.webkit.org/changeset/49233> 152988 7 commit-queue 2009-10-07 01:23:44 -0700 All reviewed patches have been landed.
