Thanks.  I checked out the 2.11 version that Ubuntu 18.04 shipped and
found the problem:

    Update the keymaps with the ones generated by qemu-keymap

Prior to this commit, this file said it was generated from XKB, and was
much smaller, not including the scan code for that other key.  This
commit added the 0x56 bar translation with altgr, and it wasn't until
after 2.12 those smarts were inserted to pick the scancode that matches
the current modifier keys.
