I’m working with TinyMCE version 7 and noticed a potential issue with the license key validation. In the tinymce.js file, the license_key configuration option seems to only check the length of the provided key to determine its validity. This means that if I supply a random key that satisfies the length requirement, it passes as valid.

I experimented by providing various random keys that matched the required length, and they all seemed to work without any issues. Given this, I have doubts about whether TinyMCE performs any real-time validation of the license key beyond this basic length check.

I expected that TinyMCE would have some form of real-time or server-side validation to ensure the license key is genuinely valid, rather than just relying on the length of the key.
