Wrong variable type after being reasigned

[str]

I'm hinting the class to a $variable, because I'm setting the class on runtime. After that, the $variable changes it's type, hinted by a method, but the new type is not reflected, and the old type is still used, which is wrong

1. setting the $field as AbstractField

2. confirming $field is an AbstractField

3. overwriting $field with $field->html() which returns a string, so $field should be a string now

4. but vscode still thinks $field is an AbstratField, not a string
