Clicking a link handle disables linking

[ebaratte]

On each chart item, link handles (blue dots) can be dragged from to create links between different items.

The specific issue arises when clicking (instead of dragging from) a link handle: the handle itself, as well as all other handles are permanently disabled. One needs to fully reload the chart to make it work again.

After a bit of investigation, I believe that the issue lies in

ngx-gantt/packages/gantt/src/components/bar/bar-drag.ts

Line 285 in 2373719

dragRef.beforeStarted.subscribe(() => {

: clicking the handle emits the beforeStarted event, but no other events are emitted when releasing the mouse button (in particular the ended event)
