How can I add custom attribute on an existing HTML tag?

1. I want to add a custom attribute on existing HTML tag e.g. I want to parse this <h1 style = "color:#FFFFFF;">This is colored header<h1>
2. When attribute is handled in custom tag handler header is not shown correctly because tag handler has been overridden.

Hello @hakobyan1221 ,

unfortunately you would need to provide the whole tag handler in order to parse additional attributes
