@AnmolChauhan1234 thank you for giving this a go! This feels very heavy-handed to me though, I’m not sure how you arrived at this solution? I would have preferred to see simpler approaches attempted before we move to re-parsing and rewriting all HTML in a filter.
There are also a lot of unrelated and unnecessary changes in your PR, it’s not clear to me if you did this with an AI coding tool and didn’t check the output?
I would like to see this attempted with customizations to our markdown and reStructuredText rendering. Unless there is a reason why it’s not possible? We really shouldn’t be rewriting all blog post HTML just to add one attribute to one type of element.

There are no images in this content so those changes are irrelevant
