iOS not calling my Quick Look extension for RAW files recognized by the system

I'm the developer of Camera RawX (avail on the Mac App Store).

I'm working on Camera RawX for iOS to provide Quick Look support for camera RAW files not supported by iOS.

I use the Files app to open a RAW file to invoke Quick Look on my iPad (it is running iOS 17.6.1).

The RAW file in question is a Fuji compressed RAF file.

When I tap on the RAF file, iOS opens the Quick Look window, but my app's Quick Look extension is not called.

If the RAW file in question is a Sigma Foveon X3F file, a file that has no native Apple RAW support, then my Quick Look extension is called and I'm able to display the image in the Quick Look window without issue.

It seems that a system recognized RAW file extension (RAF in this case), is not triggering my Quick Look extension. On the macOS, this works fine without any issue.

The strange thing is that my Thumbnail extension is being called when the RAW files show up in Files. Even if it is a RAF file. So it seems like a bug to me or am I missing something crucial in my Info.plist file?

Info.plist for the app. I tried to add UTExportedTypeDeclarations for Fuji RAW Image to see if I can use my own UTI, but it makes no difference.
