This must be a Chrome thing, not an Android thing, no? I didn't test this but I'd be surprised if Firefox behaved the same.
Or Firefox would still be using android's file system / upload process, which probably hands off the photos with geotags stripped already.
I'm pretty sure this is what happens in the iPhone at least, so I'd imagine it is the same in Android.
Just tested with Firefox 149 on Android 13. There are no coordinates when I upload an image to EXIF viewer web sites.
