Why does Firefox 50.0 believe I have no keyboard?

Firefox 50.0 pops up the on-screen keyboard on my Lenovo X230 tablet running Windows 8.1 Professional whenever I set focus in an editable text box, even though I am using its physical keyboard.

about:config shows two properties as "user set" which I have not set: ui.osk.debug.keyboardDisplayReason;IKPOS: Lack of keyboard confirmed. ui.osk.on_screen_keyboard_path;"C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe"

Resetting the above properties is ineffective. They acquire the above-described values again immediately as soon as I set focus in a text box. Why does Firefox believe that I have no physical keyboard?

This behaviour is peculiar to Firefox 50.0 and has never occurred with any other application nor with any previous version of Firefox. It is independent of the website being browsed. I have restored proper operation using the physical keyboard by setting: ui.osk.enabled;false in about:config

However, this will presumably make it difficult for me to use Firefox on my laptop in tablet mode.

Please try changing the ui.osk.detect_physical_keyboard value to true in the about:config page.

If that doesn't work, please try reinstalling your keyboard device driver from the Windows Device Manager.

Changing the ui.osk.detect_physical_keyboard value to true did not help. As a "quick and dirty" solution, I have simply set ui.osk.enabled to false, rather than reinstall my keyboard driver (which MS claims is the newest).
