Maximum text length for a custom visual property?

[wildert]

I am developing a control that requires me to store some configuration json inside a property, and the UI limits length to 250 characters, but i'm able to store much more using the API, I stopped at 1,000,000 characters. Is there a maximum supported length?

As far as I know, there's no an explicit limitation but saving might fail if tyr to keep more than 1MB data.
