Bug 1347433 part.3 TextEventDispatcher::PendingComposition::Flush() should replace native line breakers in the composition string before dispatching composition event r=m_kato So, finally, Flush() should replace native line breakers in the composition string before dispatching composition events. However, if the composition string was set by Set(), i.e., it's already been replaced with native line breakers, we shouldn't try to do it again due to performance reason. Therefore, this patch adds |mReplacedNativeLineBreakers| to manage if it's already been called. MozReview-Commit-ID: 5Y7ULWeP153
