official jQuery UI mouse widget source _mouseMoveDelegate _mouseUpDelegate _mouseStop document mouseup

💡 Result:

The **official jQuery UI mouse widget source** is [`ui/widgets/mouse.js`](https://github.com/jquery/jquery-ui/blob/main/ui/widgets/mouse.js) in the jQuery UI repository. ([github.com](https://github.com/jquery/jquery-ui?utm_source=openai))

In the current `main` source, `_mouseDown` creates `_mouseMoveDelegate` and `_mouseUpDelegate`, then binds them to the widget’s `document` for `mousemove` and `mouseup`. On mouseup, `_mouseUp` unbinds both delegates and calls `_mouseStop(event)` if a mouse interaction had started. ([github.com](https://github.com/jquery/jquery-ui/blob/main/ui/widgets/mouse.js))

The source also has a document-level `mouseup` handler that resets the shared `mouseHandled` flag; that is separate from the per-widget delegate that runs `_mouseUp`. ([github.com](https://github.com/jquery/jquery-ui/blob/main/ui/widgets/mouse.js))

This is the current `main` branch; you didn’t specify a release version.

Allow drag events over loading placeholders.

When a loaded field is dragged, jQuery UI uses document-level mousemove and mouseup handlers. The capture handler stops those events inside .frm_field_loading, so handleDragStop() may not run and the drag UI can remain active.

Keep blocking other placeholder interactions, but remove only mouseup and mousemove:

Suggested fix 
- [ 'click', 'dblclick', 'mousedown', 'mouseup', 'mousemove', 'mouseover', 'mouseout', 'contextmenu' ]
+ [ 'click', 'dblclick', 'mousedown', 'mouseover', 'mouseout', 'contextmenu' ]

Update the placeholder event-blocking list in the eventType iteration to stop
blocking mouseup and mousemove, so document-level drag handlers can complete.
Keep blocking the other listed placeholder interactions.

Observed live: hover a loaded field (Field 10), then move onto the placeholder below. .frm-field-group-hover-target stays on Field 10's row and the row stays highlighted until the pointer reaches another non-placeholder area, because mousemove on the placeholder never reaches maybeRemoveHoverTargetOnMouseMove on #wpbody-content. Screenshot in the review body.

Cosmetic only. If you want it gone, call maybeRemoveGroupHoverTarget() from ignoreLoadingFieldMouseEvent when the event is mouseover/mousemove, before the stopImmediatePropagation().

fieldsContainer.addEventListener( eventType, ignoreLoadingFieldMouseEvent, true );
} );
document.addEventListener( 'click', prepareInteractedFieldSettings, true );
document.addEventListener( 'focusin', prepareInteractedFieldSettings, true );
