Dragable annotations not working on touch devices

[PadWorks]

Expected behaviour

Annotations should be moved on touch devices when option draggable is set.

Actual behaviour

Dragging of annotations is not possible on touch devices (tested on Windows10, Apple and Android devices)

Live demo with steps to reproduce

Product version

Highcharts .NET v8.0.4 and v8.1.2

Hi @PadWorks

Thank you for reporting the problem.
This is a bug and probably a part of #13420

Internal note:
After remote debugging of Chrome on Android:
For a touch device (Android) an event is emitted and nothing happens here:

highcharts/ts/annotations/eventEmitterMixin.ts

Line 204 in af5fdee

fireEvent(emitter, 'drag', e);

because it doesn't match the added event here:

highcharts/ts/annotations/eventEmitterMixin.ts

Line 128 in af5fdee

addEvent(emitter, H.isTouchDevice ? 'touchmove' : 'drag', emitter.onDrag);

Those two don't match, but I am not sure which one should be fixed - @Izothep ?

@KacperMadej Removing

addEvent(emitter, H.isTouchDevice ? 'touchmove' : 'drag', emitter.onDrag); 

and using

addEvent(emitter, 'drag', emitter.onDrag); 

Is not causing issues on iOS devices. Could you please confirm on Android? If yes, the solution is to change this simple line.
