* Foot process(es) sometimes remaining, using 100% CPU, when closing
multiple foot windows at the same time
(https://codeberg.org/dnkl/foot/issues/542).
* Regression where `<mod>+shift+tab` always produced `\E[Z` instead of
the correct `\E[27;<mod>;9~` sequence
(https://codeberg.org/dnkl/foot/issues/547).
