existingdir with default validated and stops program run on unused-subcommand

Summary
If you have multiple subcommands, which have constrained arguments (e.g. existingdir
with default
values) those constraints must pass even if the subcommand is not invoked.
I would expect uninvoked subcommands to NOT interrupt program run.
Kong Code
type Options struct {
Cmd1 Subcommand1 `cmd:""`
Cmd2 Subcommand2 `cmd:""`
}
type Subcommand1 struct {
Dir1 string `group:"dir" help:"get a directory" type:"existingdir" default:"dir1"`
}
type Subcommand2 struct {
Dir2 string `group:"dir" help:"get a directory" type:"existingdir" default:"dir2"`
}
Output
$ mkdir -p dir1 && go run main.go cmd-1 --dir-1 dir1
--dir-2: stat /Users/dsasser/personal/kong-bug-demo/dir2: no such file or directory
exit status 1
Expected Output
The expectation is that the program would run, as the constraints on the operable subcommand have been satisfied.
Note that if the default
value is left off the parameters in the subcommands, the program runs as expected.
