Created attachment 461485 [details] Screenshot of the error The code: <a href="" download="this.html">Download this page</a>` Should prompt the user to download the current page and save it as a file called "this.html" On iOS, a download prompt appears, the file is created, but it is zero bytes. Demo: https://shkspr.mobi/blog/2021/08/to-download-this-page-click-here/ Evidence: * https://twitter.com/pekingspring/status/1556601701603352576 * https://twitter.com/Bari10/status/1556538357353693187 * https://twitter.com/rgarner/status/1556530227676946432 * https://twitter.com/billt/status/1556528760056422401 On MacOS Safari, the file downloads correctly and has the correct file size. (I've also raised this as FB11144571 on Feedback Assistant - because I wasn't sure if it was an iOS or WebKit bug.)
