LibWeb: Implement the DataTransfer files attribute 2024-08-17 14:44:26 -04:00			`#import <FileAPI/FileList.idl>`
LibWeb: Implement the DataTransfer items attribute 2024-08-20 18:44:22 -04:00			`#import <HTML/DataTransferItemList.idl>`
LibWeb: Implement the DataTransfer files attribute 2024-08-17 14:44:26 -04:00
LibWeb: Add an empty DataTransfer IDL implementation This does not implement any of the IDL methods, but GitHub requires the interface exists to upload files via an <input type="file"> element. Their JS handles uploads via this element and via drag-and-drop in one function, and check if the uploaded file is `instanceof DataTransfer` to decide how to handle it. 2024-03-13 15:35:39 -04:00			`// https://html.spec.whatwg.org/multipage/dnd.html#datatransfer`

LibWeb: Use 'FIXME' extended attribute where possible This improves the debuggability of many live web pages :^) 2024-05-19 22:15:54 +12:00			`[FIXME] undefined setDragImage(Element image, long x, long y);`
