If given `nsPresContext` is for a lazy loading `<iframe>` and the frame has not been loaded yet, its `GetTextInputHandlingWidget()` may return `nullptr`. However, `IMEStateManager::sTextInputHandlingWidget` may have already cache it. Therefore, `IMEStateManager` should use: * `sTextInputHandlingWidget` if it's available * otherwise, `nsPresContext::GetTextInputHandlingWidget()` Differential Revision: https://phabricator.services.mozilla.com/D197991
