Bug

What is the expected behavior?

For format(value,'FR','National');

• +33123456789 => 01 23 45 67 89
• 0123456789 => 01 23 45 67 89

For format(value,'FR','International');

• +33123456789 => +33 1 23 45 67 89
• 0123456789 => +33 1 23 45 67 89

What is the current behavior?

For format(value,'FR','National');

• +33123456789 => 01 23 45 67 89
• 0123456789 => 0123456789

For format(value,'FR','International');

• +33123456789 => +33 1 23 45 67 89
• 0123456789 => +33 0123456789

Is there anything else we should know?

It's working good on the demo : https://catamphetamine.github.io/libphonenumber-js/

What is the current behavior?

On the demo page, if I set country to FR then

For format(value,'FR','National');

• 0123456789 => 01 23 45 67 89

For format(value,'FR','International');

• 0123456789 => +33 1 23 45 67 89

Therefore it's working.

Make sure to supply a parsed number to format. https://github.com/catamphetamine/libphonenumber-js#formatparsednumber-format-options

Alternatively you could create a PR with a test case illustrating the issue. Closing it otherwise.
