I'm facing exactly same problem, as @RByers described:
In the app I'm working on users should be able to move elements inside a scrollable container.

As soon as touchstart fires, container should lock it's position so user is able to drag elements, without panning around.

It's not possible to achieve by adding the `touch-action: none;` property - it has no effect after touchstart.
Two possible workaround I found are: 
- register _touchstart_ event implicitly as non-passive and run _preventDefault_ inside a listener
- change to _overflow: hidden_ for scrollable container (scrollbars disappear and layout changes)
