The behavior has changed when specifying an xlsx file in the src of iframe in my PWA app.

The behavior has changed when specifying an xlsx file in the src of iframe in my PWA app.

On iPadOS 17.3:Content of xlsx file shown in iframe On iPadOS 17.5.1:A screen appears on top of the original screen to select an app to open the xlsx file.

I would like to restore the original behavior, but how can I do that?

In addition, if i open and operate the same URL as the one opened in the PWA app in Safari on iPadOS 17.5.1, "download test.xlsx dialog" is open and the dialog has view or download buttons.

If the behavior has changed to same to safari on iPadOS17.5.1, it is good for me.
