/** |
| 2 |
* Desktop Mode — Media Library drag-and-drop enhancement. |
| 3 |
* |
| 4 |
* Injects draggable=true on every .attachment tile in the WordPress |
| 5 |
* Media Library (grid view AND modal view) and wires a dragstart |
| 6 |
* handler that populates DataTransfer with multiple MIME types so the |
| 7 |
* drag works in many drop targets: |
| 8 |
* |
| 9 |
* text/plain — the attachment URL |
| 10 |
* text/uri-list — same URL, standards-compliant |
| 11 |
* text/html — <img> tag for images, |
| 12 |
* <a> tag for other files, |
| 13 |
* so rich text editors |
| 14 |
* (TinyMCE, contenteditable) |
| 15 |
* natively accept the drop |
| 16 |
* application/x-wp-media-attachment — JSON blob with id, url, |
| 17 |
* title, alt, mime, sizes — |
| 18 |
* for WP-aware drop zones |
| 19 |
* that want the full record |
| 20 |
* |
| 21 |
* The script is a vanilla IIFE with no build step. It is intentionally |
| 22 |
* defensive: |
| 23 |
* |
| 24 |
* - runs only when wp.media exists, |
| 25 |
* - idempotent (each tile is enhanced at most once), |
| 26 |
* - uses a MutationObserver so tiles added later (user switches |
| 27 |
* folder, scrolls, opens a different media frame) are enhanced |
| 28 |
* too, |
| 29 |
* - never removes or interferes with WordPress's own click / focus |
| 30 |
* handlers on the tile. |
| 31 |
