Korean input does not work in Firefox only
I recently got Windows 10 set up with a Korean keyboard, but when I go to Firefox, the language remains English. To wit, I am typing this right now with the Korean keyboard selected. Tabbing out to a different program works as expected.
When I try to switch the keyboard, it doesn't matter which is selected--it always types in English.
I could find no troubleshooting help online for this.
Why is Firefox ignoring my input language?

Note that Windows remembers the keyboard layout per application, so you should switch the layout to Korean while Firefox has focus.
