Context

• node version: 10.16.3
• joi version: 16.1.2
• environment: browser
• used with: standalone

What are you trying to achieve or the steps to reproduce ?

When I use this:

Joi.string().email({ tlds: false }).required()

Which result you had ?

I get error:

But when I toggle option "ignoreLength" to true, like this:

Joi.string().email({ tlds: false, ignoreLength: true }).required()

All works properly.

I think this issue must be fixed.

P.s.: Thank you so much for Joi. It very much helps 😀
