Safari viewport suddenly becomes half size. I have come across two places where this happens:

1.
When clicking on a deep link in an email in Gmail app and the link opens in Safari. The page is half size.

2.
When I view PDF file in installed PWA and take a screenshot and then return to the app "Safari", the page is half size.

Thank you for the report. Could you please confirm whether this is an iOS 17 regression?

Also, I have personally never seen this, including in the Gmail app.

I get different responses back from my users. It has been there for several months, they say. They all say iOS 16, but they can't remember the exact version where it started.
