Bug#1001809: libsdl2/2.0.18 breaks osk-sdl autopkgtest: Testing osk toggle button and 'mouse' key input

The osk-sdl autopkgtest on ci.debian.net seems to show a regression when
run with libsdl2 (>= 2.0.18):

                         pass            fail
libsdl2                  from testing    2.0.18-3
osk-sdl                  from testing    from testing
all others               from testing    from testing

The test output is:

> ** Testing osk toggle button and 'mouse' key input
> ERROR: Unexpected result!
> 	got:
> 	expected:       qwerty

This could be either a regression in libsdl2, or a pre-existing bug
in osk-sdl. I don't use osk-sdl myself, so I don't really have a reference
for what it's doing here. When someone works out what is going on, this
bug should be reassigned to either libsdl2 or osk-sdl as appropriate.

(The previous stage of the autopkgtest, involving
test_keyscript_no_keyboard_phys, already failed but the failure was
ignored; I've reported that as a non-RC bug in the osk-sdl source package,
but it is not a regression.)
