Comment:
I found an article titled [http://www.the-art-of-
web.com/javascript/doublesubmit/ JavaScript: Preventing Double Form
Submission] which might be worth reviewing. In particular, it points out
"Rather than simply disabling the button, we can also change the text so
that people don't get confused."
Did you consider trying to add some tests for the patch?
I share Nick's concern on the pull request that this may have a good
chance of causing some regression in unconsidered edge cases. I'm not sure
if it's considered a best practice these days. The article suggests that
some browsers (e.g. IE11) treat a double click as a single click. It
seems unfortunate if every project has to add something like this.
