Custom props text-decoration-line is selected on parent but not reflect on the style manager of child

[Bernie05]

Hi, newbie question regarding adding a new custom property in typography, So this is the case if I'm going to change the value from the parent for example text-align this will take effect on the child component and also display the value on the property in style manager, but when I try to the custom component that I did, which is text-decoration-line, yes the style in the child component is applied but when you visit the style manager property this will not reflect.

Thanks in advance.
