This is fixed now, so your original case is supported,
as well as more cases reported in e.g.
https://lists.gnu.org/archive/html/emacs-devel/2021-04/msg00083.html
https://lists.gnu.org/archive/html/emacs-devel/2021-08/msg00962.html

The behavior can be customized by the new user option 'repeat-check-key'.
Also a command can have a symbol property with the same name
and two values: 't' checks the key when the variable is nil,
and 'no' doesn't check the key when the variable is t.

A special property 'no' is necessary instead of using 'nil',
because 'get' can't distinguish when the property has the
value 'nil' and when there is no property set on the symbol.
Also there is no function to delete a property from a plist,
so every package invents own wheel, e.g. map--plist-delete.
org-plist-delete-all, svg--plist-delete...
