Tab restore: about:srcdoc

Repro page for an iOS tab-restore bug. It mimics ad scripts that load a placeholder URL in an iframe and then render the creative with srcdoc.

Steps

  1. Open this page in Prisma Browser on iOS 27.
  2. Wait until the status below says Done, about 2 seconds.
  3. Kill the app from the app switcher and reopen it.

Bug: the tab reopens as an about:srcdoc error page, or a blank page.
Fixed: the tab reopens on this page.
