kinit() sets up the XKB extension, after which the server stops sending
core MappingNotify to this client, so the refresh branch never fired and
strans kept its startup keymap; setxkbmap after launch left every XIM
key resolved against the old layout. Select XKB NewKeyboardNotify and
MapNotify (with the map parts, or MapNotify is never delivered) and
rebuild the keymap on those events instead.
