Tab restore: about:srcdoc
Repro page for an iOS tab-restore bug. It mimics Google ad tags: a friendly iframe whose creative iframe loads about:blank and then switches to srcdoc.
Steps
- Open this page in Prisma Browser on iOS 27.
- Wait until the status below says Done, about 3 seconds.
- 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.
