Current behavior
Moving the splitter to the left repeatedly throws an error
"TypeError: Cannot read property '0' of undefined
at Splitter.onResize (splitter.ts:147)

Expected behavior
No error thrown

Minimal reproduction of the problem with instructions
Like I said in #10176, you need to drag the splitter from right to the very far left (further than the div) several times (a dozen) to make it happen.

What is the motivation / use case for changing the behavior?
I'm not sure here, but it seems that 'event.changedTouches' is undefined sometimes

As pointed by @Blafy the issue still persist in the new version. One tip to replicate keep the dragging to outside the div and do not mouseup
