I'm seeing some multilingual SVG File: pages that do not offer to show the translated languages ("Render this image in ...").

These files are small, so they are not the SVG file greater than 256 kB issue raised in T270889.

Many of the files do not have systemLanguage="en" clauses.

List of steps to reproduce (step by step, including full links if applicable):

None of these File: pages display the render this image in language dropdown:

• https://commons.wikimedia.org/wiki/File:Celltypes.svg (99 kB) this has nine languages... (no systemLanguage="en")(metadata)
• https://commons.wikimedia.org/wiki/File:1263_Mediterranean_Sea-es.svg has systemLanguage="eu" and the default clause is Spanish. (no systemLanguage="en")(metadata)
• https://commons.wikimedia.org/wiki/File:Minsk_Protocol.svg (systemLanguage="eu" and default clause is English)(metadata)
• https://commons.wikimedia.org/wiki/File:Eukaryotic_DNA_replication.svg (has systemLanguage="fr")(metadata)

Here's an even odder case. Go to

• https://commons.wikimedia.org/wiki/File:2022_Russian_invasion_of_Ukraine.svg or (metadata)

• https://commons.wikimedia.org/w/index.php?lang=en&title=File%3A2022_Russian_invasion_of_Ukraine.svg

They will display the language drop down box.

Now select the "(default language)" option and click GO. The language dropdown box is not present on the new page

Selecting the default language is the same as going to

• https://commons.wikimedia.org/w/index.php?lang=und&title=File%3A2022_Russian_invasion_of_Ukraine.svg

Alternatively, ask for the Klingon version of the page, which does not have a render this image in (language) selector either:

• https://commons.wikimedia.org/w/index.php?lang=tlh&title=File%3A2022_Russian_invasion_of_Ukraine.svg

What happens?:
The language dropdown box is not displayed on the File: page even though translations are present.

What should have happened instead?:
The dropdown box should display for any SVG File: page that has translations.

Apparently, the dropdown box only displays if no HTML lang parameter is given and the file has systemLanguage="en" or if an HTML lang parameter is given, then the file must have that systemLanguage.

For example, specify lang=eu for the eu-only Minsk Protocol.svg above provides a dropdown:

• https://commons.wikimedia.org/wiki/File:Minsk_Protocol.svg?lang=eu
