Support for mark and note on PDF like the old edge.

I start to use the new edge a month ago, but it seems incomplete when I do things on PDF. The old edge has the function to mark and note on PDF while the new one hasn't, please add it to the new one. It's useful for me, and I think it's useful for everyone who often reads PDF articles.

This is how the new edge displays the notes made in the old edge, please fix this bug. The language I use is Chinese. Thanks!
