When `TextComposition` in a content process requests to commit composition, the request is sent to the parent process synchronously. Then, if IME handles the request synchronously, `PuppetWidget::RequestIMEToCommitComposition` dispatches a `eCompositionCommit` event synchronously. However, if IME handles it asynchronously, `RequestIMEToCommitComposition` does nothing and `TextComposition::RequestToCommit` dispatches `eCompositionCommit` or `eCompositionCommitAsIs` before receiving next event (in the most cases). However, the puppet widget won't receive the delayed commit event in this case because `TextComposition::DispatchCompositionEvent` in the parent process does not send the delayed commit event. Therefore, `PuppetWidget::DispatchEvent` cannot notify `TextEventDispatcher` of the commit event. Therefore, `TextEventDispatcher` will have wrong composition state. So, fixing this issue, we need to make `TextComposition::DispatchCompositionEvent` in the parent process should send the commit event as usual. To avoid the `ContentCacheInParent` to misunderstand the native IME's composition state, `TextComposition::RequestToCommit` should not dispatch `eCompositionCommit` nor `eCompositionCommitAsIs` because the event causes `ContentCacheInParent` thinks the composition is actually committed in IME.
