Twenty Seventeen iPadOS front page featured images

This issue affects the the display of images on the front page of sites using the Twenty Seventeen theme, when viewed on the new iPadOS 13.1.

The main image at the top of the front page is OK. However, all featured images of pages in the panels in sections down the front page are magnified (zoomed in) to the point where the image is unrecognizable.

The same featured images on the respective individual pages display OK on that page.

Example sites:
elementsofhyams.com
compactrv.net
kiamacycles.com.au

I have tested this on multiple devices, across several sites. The only devices affected are those running iPadOS 13.1

Twenty Seventeen front pages display OK on desktops, laptops, on iPads running earlier versions of iOS, and on iPhones with iOS 13.1 installed. But not on iPadOS 13.1.

Any suggestions as to a possible cause, and ideas on how to remedy this issue, greatly appreciated.

Thanks,
Warren
