sub command options are printed in single line in help text

[evgnomon]

My urfave/cli version is

2.17.1

Checklist

• My project is using go modules.
• My project is automatically downloading the latest version.

Describe the bug

Here is the printed text for option helps:
https://go.dev/play/p/US17m1KeEib

--itemNo value, -i value  option 1--output value, -o value  option 2 (default: no write to file)

While it should be in multiple lines i.e.

--itemNo value, -i value  option 1
--output value, -o value  option 2 (default: no write to file)

To reproduce

https://go.dev/play/p/US17m1KeEib

package main

import (
	"log"

	"github.com/urfave/cli/v2"
)

func main() {
	app := &cli.App{
		Name: "protodump",
		Commands: []*cli.Command{
			{
				Name: "message",

				Aliases: []string{"msg"},

				Subcommands: []*cli.Command{
					{
						Name: "subcomm",

						Flags: []cli.Flag{
							&cli.StringFlag{
								Name:     "itemNo",
								Required: true,
								Aliases:  []string{"i"},
								Usage:    "option 1",
							},
							&cli.StringFlag{
								Name:        "output",
								Aliases:     []string{"o"},
								DefaultText: "no write to file",
								Usage:       "option 2",
							},
						},
						Action: func(c *cli.Context) error {
							return nil
						},
					},
				},
			},
		},
	}

	err := app.Run([]string{"app", "msg", "subcomm", "--help"})
	if err != nil {
		log.Fatal(err)
	}
}

Observed behavior

options printed in a single line for help text. This issue is not happening in all platforms. We have seen in in Windows and The playground but not in macOS.

Expected behavior

Print option help in separate lines.
