That is what I would expect to ensure accessibility for non-sighted users using VoiceOver on iOS, which is why this one is set to behave in this manner.

Otherwise it is impossible for a blind screen reader user to know that a list of suggested options has dynamically appeared, nor if the newly rendered content is relevant to their search criteria while typing. A sighted user has the advantage of glancing at the suggested items list while typing, but the only way for a blind person to receive the same level of information is to announce the first most-relevant search result.

I just confirmed this works correctly on the above template in iOS16 using an iPhone and iPad, both with a bluetooth keyboard and without one connected.

This particular behavior, however, is not part of the design pattern for Combobox in the ARIA spec, so it is likely that most developers will not think to add it.
