Problem/Motivation
jQueryUI is going to be deprecated
jquery.ui.draggable is among the components that need to be addressed
As mentioned in the parent issue: #3067261: [Plan] Remove jQuery UI components used by Drupal core and replace with a set of supported solutions
The OpenJS Foundation lists jQuery UI as an Emeritus project in https://openjsf.org/projects/ which is described as:
Emeritus projects are those which the maintainers feel have reached or are nearing end-of-life
Proposed resolution
When #2158943: Replace jQuery UI dialog with supported library or polyfill and #3064049: Replace jQuery UI sortable with Sortable js are committed, deprecate the jquery.ui.draggable library.
No replacement will be necessary as the two issues above remove all uses of jquery.ui.draggable from core.
Remaining tasks
Wait for #2158943: Replace jQuery UI dialog with supported library or polyfill and #3064049: Replace jQuery UI sortable with Sortable js to be completed, then change the issue status to Active (or any other flavor of not-postponed)
Deprecate the jquery.ui.draggable library.
