[css-overflow-4] Should block-ellipsis clip ::before/::after text?

[fantasai]

One of the use cases for line-clamp etc. is truncating blockquotes, but there's a problem with the end quotation mark getting dropped when the text is ellipsized.

Should we exempt ::before/::after from trunctation and place it after the ellipsis?

Related issue for text-ellipsis: #9541 That one's trickier because you'd need to be tracking the stack of opening/closing punctuation.

Yes, it might help us to attach a button style feature after the ellipsis.
This button is a very common pattern in actual web pages or components.

What if the ::after has lots of contents that would increase the number of lines?

I'm also not sure if it makes sense to always do this for ::after, and I could see authors wanting this behavior for a real element (e.g. in @yisibl's example the button should probably be an actual <button> so that it's keyboard navigable and such).

So should we have a property to control this?
