Correct me if I am wrong!
I’ve just stumbled upon “bug” where using Block level content attribute with control such as input, or textarea and perhaps auto - does not escape <> - which can lead to unexpected behaviour. So for example if someone has custom block with such attribute - from panel controls person can input the <> tags, script and etc. Perhaps someone needs this kind of behaviour.
Although to be on a safe side - if someone requires such a behaviour perhaps checkbox could appear in Pinegrow “escape input”? I understand that additional logic is required in the output of code generation.
On the other hand - when using rich text - it does behave as intended(this statement has not been tested extensively).
