I like the ability to capture HTML pages together with images into one PDF document.

Unfortunately the web has changed and many web pages use Javascript to fill out the DOM tree, as a result content is missing from pages like:

https://ropercenter.cornell.edu/ipoll/search?q=dreams

which makes a blank page PDF. There are tools out there that can make a capture of modern web pages using Chromium, PhantomJS, or HTMLUnit to run the Javascript. One can be found here:

sometimes these work, but the WARC file and the WARC file players are awful. It reminds me of the times that you go to the wayback machine and give up looking for something because the pages take too long to load and are always missing something.

It's a tricky problem for a few reasons, not least that you're never 100% sure that the important Javascript on a page is done running.

That's what makes it a problem for Adobe and why it should be supported by the #1 document conversion tool.

To be specific I'm rejecting the WARC "archive-the-conversation" approach and wanting something that makes an HTML DOM tree and then turns that DOM tree into a good-looking PDF -- I don't want interactive features preserved in the PDF
