The current Beta feature preference of the FileExporter extension doesn't have a right-to-left (RTL) image. All other beta features on Arabic Wikipedia have RTL-ed images except this one.
- The existing LTR image in the code: https://github.com/wikimedia/mediawiki-extensions-FileExporter/blob/master/resources/FileExporter-beta-features.svg

It's probably fine to mirror the existing image. It would be awesome if a person with knowledge about right-to-left wikis can confirm it looks ok.
