Chromebook Flip in tablet mode: on-screen keyboard does not appear

Tapping on "keyboard" in the left drawer, as suggested in #320 , doesn't help.

If I turn on the ChromeOS accessibility setting that gives a button to show the touch keyboard anytime, the button does work with termux. However, having that setting enabled also forces the touch keyboard to a layout where the keys are smaller than the default one (even during normal web browsing) so it is not ideal.
