disableAutoFill does not seem to support the formaction attribute

[rossdonald]

This script is great, I find it really useful but I need to use formaction in some of my code to use different handlers and it seems like it is not supported.

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/submit#formaction

Here is a fiddle. It should go to /test when you submit but it doesn't as the script just submits to the default location

Any ideas on how to fix this?
