Different results in FindNumbers with EC national numbers

[mngobbi]

Context

• When running FindNumbers("998039805", "EC") I don't get any results
• Using the last version of nuget 8.13.42 (tested on NET8 env)
• Checked against https://libphonenumber.appspot.com/phonenumberparser?number=998039805&country=EC

Workaround

I instead of using FindNumbers("998039805", "EC") directly I do this instead:

var prefix = instance.GetCountryCodeForRegion(countryCode);

numbersFound = instance.FindNumbers(prefix + value, "EC");

I get the expected results...

I am missing something?

Thanks!

You did find some curious behavior, I'm not sure I'll be able to get to the bottom of it this weekend but I'll dig into it.

Also, thank you very much for filling out the issue template! I think you might be the first to do so in 2+ years.

It seems to be failing due to NationalPrefixOptionalWhenFormatting being false here: https://github.com/twcclegg/libphonenumber-csharp/blob/main/csharp/PhoneNumbers/PhoneNumberMatcher.cs#L654.
I'll need to remember how to spin up a project with the Java version to compare.
