iOS 18 crash: GiphyGridController switch from gifs -> stickers

[AndrewSB]

🐛 Bug Report

On iOS 18, there's a crash when switching the GPHMediaType. in the case where there were results for the media type you were on, and there are no results for the one you're switching to

To Reproduce

(Write your steps here:)

1. Open a view with the GiphyGridController and perform a search for a gif with a text search term "warthog angel" (warthog angel has gif search results, but no sticker results)
2. See gif results
3. Switch the search to be for stickers instead of gifs, here's example code for that:

        let content =
            text.count >= 1
                ? GPHContent.search(withQuery: text, mediaType: mediaType, language: .english)
                : GPHContent.trending(mediaType: mediaType)

        currentSearchTerm = (text, mediaType)
        giphyGridController.content = content
        giphyGridController.update()

Expected behavior

show an empty result for stickers in the giphy grid

(Write what you thought would happen.)

Actual Behavior

I get the following crash

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Expected dequeued view to be returned to the collection view in preparation for display. When the collection view's data source is asked to provide a view for a given index path, ensure that a single view is dequeued and returned to the collection view.

can share if it doesn't seem to reproduce. i didn't do all the work to make this a reduced example, i'm hoping it's an obvious bug that can be fixed
