Attributes without values breaks the parser about diffhtml

[tbranyen]

@yatesco I don't anticipate the behavior you're describing changing 👍

Sorry :( the old parser was based off node-fast-html-parser, and as such inherited some issues. I have this fixed in the new parser, but still playing whack-a-mole with existing tests. It's getting very close!

No problem at all @tbranyen :-).

One critical bug/feature I use is the fact that it doesn't overwrite input fields if the page has newer data:

• now: input field = "abc"
• now+1 request latest from server
• now+2: input field = "abcdef"
• now+3 response from server, containing "input field=abc"
• now+4 merge complete

Crucially, the input field contains "abcdef" not the "abc" from the server. I rely on this, so can we please keep this behaviour (albeit behind a config option maybe?"
