Text helper limitation to 255 characters is workaround

[cedricdelecole]

The problem

Hi there,

It seems to be a limit of 255 characters when creating a text helper, using the arrows to set the min and max limit.
I was having an issue by sending the output of an AI generative answer to that helper, where the AI was not limiting the output to 255 characters as I was asking ... But I am surprised I was somehow able to increase the text help size (in my case 2555 characters) ...

Wondering if this is really a limit or I was able to bug the system ??
