Splitter event listeners get ignored

[nabsta-eth]

Hi! Great package. We've been using it for a couple of years and have done some pretty cool stuff with it and only now have I found something that I can't find do with it out of the box! 😉
I currently use buttons manually placed on the splitters for collapse/expand of side tabsets left/right but would also like to have the ability to double-click a splitter to "snap" a tabset to it's minimum (or a default) width.
Any event listener I add manually gets ignored, presumably due to preventDefault()s internally.
