bug: Can't execute a custom decorator after @Prop decorator

[luenmuvel]

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Stencil Version

4.0.0

Current Behavior

It is not possible to add a custom decorator after the @prop decorator. Calling to "Custom Decorator" is cancelled for some reason. When I use the same Custom Decorator without the @prop decorator it does run:

@Prop() CustomDecorator() myProp;

This doesn't work. But this one does:

CustomDecorator()
Another()
Other()
myProp;

Expected Behavior

I would like to be able to work with custom decorators that allow me to perform certain actions before assigning the value to the property, like so:

@Prop() ParsingData() MyProperty;

In this way, it could execute actions depending on the type of information it receives, before assigning the value to the property "MyProperty"

Hey @luenmuvel, sorry you're running into this issue. I believe this is a duplicate of #3831 which is already on our radar - we have plans to fix this and to enable Stencil users to write with custom decorators. Accordingly I'm going to close this, but not because I don't think it's important!

Thanks for filing 🙂
