Parsing error on positional arguments after mixing a multiple-valued positional arg with a flag

Rust Version

cargo 1.74.0-nightly (925280f02 2023-08-25)

Clap Version

4.4.2

Minimal reproducible code

use clap::Parser;

#[derive(Parser, PartialEq)]
pub enum Subcommand {
    Compress {
        #[arg(required = true)]
        files: Vec<String>,

        #[arg(required = true)]
        output: String,

        #[arg(short)]
        verbose: bool,
    },
}

fn main() {
    let inputs = [
        "ouch compress a b c output -v",
        "ouch compress a b c -v output",
        "ouch compress a b -v c output",
        "ouch compress a -v b c output",
        "ouch compress -v a b c output",
    ];
    let expected = Subcommand::Compress {
        files: ["a", "b", "c"].map(Into::into).to_vec(),
        verbose: true,
        output: "output".into(),
    };

    for input in inputs {
        let result = Subcommand::try_parse_from(input.split_whitespace());
        let result = result.map(|ok| ok == expected).map_err(|_| ());
        println!("{input}, {result:?}");
    }
}

Outputs:

"ouch compress a b c output -v", Ok(true)
"ouch compress a b c -v output", Err(())
"ouch compress a b -v c output", Err(())
"ouch compress a -v b c output", Err(())
"ouch compress -v a b c output", Ok(true)

Steps to reproduce the bug with the above code

cargo run

Actual Behaviour

Parsing fails in 3 out of the 5 cases provided in the example.

Expected Behaviour

Succeed in all 5 cases.

Additional Context

With this definition, the following input parses OK:

Compress {
    #[arg(required = true)]
    files: Vec<String>,

    #[arg(required = true)]
    output: String,
},

"ouch compress a b c output" // parses ok!

And, with this definition, the following inputs parse OK:

Compress {
    #[arg(required = true)]
    files: Vec<String>,

    #[arg(short)]
    verbose: bool,
},

"ouch compress a b c -v" // parses ok!
"ouch compress a b -v c" // parses ok!
"ouch compress a -v b c" // parses ok!
"ouch compress -v a b c" // parses ok!

So, I assumed that merging both would work, but it doesn't (in 3/5 cases).

Repeating here the output of Minimal reproducible Code:

"ouch compress a b c output -v", Ok(true)
"ouch compress a b c -v output", Err(())
"ouch compress a b -v c output", Err(())
"ouch compress a -v b c output", Err(())
"ouch compress -v a b c output", Ok(true)

Debug Output

"ouch compress a b c output -v" -> Ok(true))
