I don't know, a quick check in Android documentation seems to describe this quite well [0]:
If your app targets Android 10 (API level 29) or higher and needs to retrieve unredacted EXIF metadata from photos, you need to declare the ACCESS_MEDIA_LOCATION permission in your app's manifest, then request this permission at runtime.
Caution: Because you request the ACCESS_MEDIA_LOCATION permission at runtime, there is no guarantee that your app has access to unredacted EXIF metadata from photos. Your app requires explicit user consent to gain access to this information.
I made another quick check on my device, Chrome doesn't have the ACCESS_MEDIA_LOCATION permission and doesn't seem to request it at runtime, so the location info is stripped from the EXIF data (by the OS!) when a file is selected.
Chromium also seems have no feature to ask the user whether he agrees to share the stored location when uploading images, so there is probably no capability to request the permission at runtime.
Not satisfying, I know, but despite some judgements in the tickets the implementation seems to work as designed.
Instead, it could be considered a feature-request for Chrome to ask the user about this on upload, or couple the location-permission of a website to the permission to share EXIF-location data when uploading files (Although I think the logic on that is not really tight, the user giving permission to share his location now doesn't necessarily mean that he agrees to share all his locations from the past from EXIF-data)
