After updating the Insider build, third-party input methods cannot switch input modes properly

Hi Kodyon, because this started after an Insider build update, I’d report it through Feedback Hub with the exact build number and input method version. As a workaround, remove and re-add the language/input method, check for an updated IME from the vendor, and test the built-in Microsoft IME. If the built-in IME works but third-party IMEs fail, that gives Microsoft and the vendor a much cleaner repro.
