Masayuki Nakano 190b2c2740 Bug 1612802 - Make IMEStateManager stop notifying PuppetWidget of editor state changes while its StopIMEStateManagement() r=m_kato
Currently, `BrowserParent` rejects any notifications which come after
it blurs from IME focus.
https://searchfox.org/mozilla-central/rev/919607a3610222099fbfb0113c98b77888ebcbfb/dom/ipc/BrowserParent.cpp#2157,2169,2181,2192,2203,2216

But for saving unnecessary IPC messages, we should make `IMEStateManager` in
a content process stop sending notifications which occurs during its
`StopIMEStateManagement()` is called.
