When dropping a large file into egui on the web, eframe always reads the whole file---even if file drop events aren't handled. Drag a particularly large file into egui, and eframe will try to load the whole thing into memory. This isn't ideal.
It would be nice to read dropped files in parts, and only on demand. Seems that Blob.stream() is how JS usually does it, but my knowledge of web is limited.
