It occurred to me to try --with-x-toolkit=lucid instead of --with-pgtk.
Sure enough, I cannot reproduce the bug. So I think the problem is
something about how pgtk receives and processes keyboard input.
In summary: I can reproduce with pgtk running as a native Wayland
application, and I cannot reproduce with the Lucid build running under
Xwayland. In both cases, swaywm. I have retitled the bug.
Thanks.
