I don't think it does trigger a change for exactly this reason. I tried to build a Material login page a couple years back, where the placeholder became the label when you typed. I couldn't get it to work with autofill, because I couldn't find a vector to detect when autofill had happened. Here's a related issue:

It doesn't trigger a change, but you can certainly poll for non empty strings: https://jsfiddle.net/k91o1dw9/7/

Edit: That is, for the purposes of this exploit. I understand it's ugly.

That's correct - this has also been a massive issue for React, and still isn't fixed in a released version. There's a fix that was merged some time ago, pending release with React 16 [1]. There's some discussion about a 3rd party effort to back-port to 15.x.
