html.elements.object - Safari on iOS should not get passing grade

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

While the support matrix shows a passing grade for "Safari on iOS" and the <object> element, the reality is: Both of the examples on the MDN page do currently NOT work in Safari on iOS (17.4.1).

The first example including a PDF document is not showing anything at all. While the second example with the video file is just showing a placeholder icon, and not the desired video.

What browsers does this problem apply to, if applicable?

Safari

What did you expect to see?

The files which were intended to be seen.

Did you test this? If so, how?

Tested on newest iOS 17.4.1 on iPhone 13 mini.

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

There is a lot of reports about pdf files not working in <object> elements. However I could not find an official bug ticket.

Do you have anything more you want to share?

MDN metadata

Start with the html.elements.object compatibility record and compare it with the linked MDN <object> page and the reported Safari on iOS 17.4.1 behavior. Confirm the two examples' results, then update the Safari on iOS support data so the matrix no longer reports a passing grade, with repository validation passing as the completion check.
