prevent default right-click options when hideDownload is enabled

[szaimen]

For testing:

1. share a single picture or audio file and select hideDownload
2. open the link
3. right-click (or long press on Android) on the image or audio controls

Before this change:

4. See the default Browser options of which one is to download the file

After this change:

4. The default Browser options are gone

I Verified that it works on:

• Chromium based Browser on Desktop
• Chromium based Browser on Android

Please double check the documentation and make sure we properly communicate that it's cosmetic only and everything display in a browser cannot be 100% prevented from screenshot, cache retrieval.. .etc ? :)

I can do that! Can you give me a pointer where in the documentation this should be added/written?
