* Closes #4654 * Related #4667 * [x] I have followed the instructions in the PR template This PR avoids materializing the contents of a file that was dragged into an egui application on the web. It does so by storing the `web_sys::File` handle directly on WASM. This breaks the existing API of `DroppedFile` on the web, because there is no way to retrieve the bytes synchronously form a `DroppedFile` anymore, forcing handling call sites to become asynchronous. The native API remains the same. --------- Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com>
