Running iOS 15.4.1 (19E258) with <model> feature enabled I placed two <model> elements on a single HTML page. This both works as expected on macOS 12.3.1 with Safari TP 143 and iPadOS 15.5 public beta 2, but on iOS (see above) only the first .usdz content is loaded and the second does not even reserve a canvas area. This site works fine on iPadOS 15.5, but not on iOS: https://kreativekk.de/wp-content/uploads/ar/2modelNoBug.html

I expect this is an issue with constrained memory use, and we need to display a loading error icon on the page to convey that a <model> element failed to load.
