Looks like it works if you drag on a header (using either a touchscreen or a pointing device, interestingly), but if you do it on an item, it eats the event and treats it as an attempt to activate the item.
Looks like it's the embedded MouseArea in each delegate that blocks events from reaching the scrollable view.
We could port them to *Handler items, but there's sort of a conceptual incompatibility between touch-scrolling and touch-dragging, for views where items are draggable. We currently have press-and-hold bound to "show context menu," so we would have to re-arrange the UI a bit probably, to make press-and-hold-and-drag re-arrange items, while press-and-hold-and-release-without-moving opens a context menu.

Git commit 66507b5df163071128a90983d10f699aa1a9b3cf by Noah Davis. Committed on 16/08/2022 at 03:01. Pushed by ndavis into branch 'master'. Disable Drag and Drop for touch, fix drag and drop icons Drag and drop conflicted with drag/flick scrolling and drag and drop was deemed less important than scrolling or opening the context menu for touch. Maybe in the future we can have a way to at least rearrange favorites with touch input. Drag and drop icons seem to have been broken by commit 0868a5ae8154d10ccc7488034bc5b6e458a17968 and are now fixed.
