[BUGFIX] Do not swallow pointerdown event in finisher configuration

With #98604, jQuery UI was replaced with SortableJS. It turns out that
filtered element, where dragging should be disabled, also calls
`preventDefault()` by default, leading to the issue that text fields
cannot get focused anymore.

As documented by SortableJS, `preventOnFilter` is now set to `false` to
allow editing text fields again whilst disabling dragging their parent
container.
