Steps to replicate the issue (include links if applicable):

• Open the Wikipedia Android app.

• Use the “Add an image” suggested edit on an article that contains an infobox (example provided by contributors in the VP thread).

• Submit the edit and review the diff or published version.

• Observe whether the app inserts parameters such as caption, image_caption, or similar fields that are not defined in the template’s TemplateData.

What happens?:
The Android app inserts the image inside the infobox and adds parameters (e.g., caption=) that do not exist in that infobox template.

The infobox produces preview warnings or displays unexpected output due to invalid parameters.

The behavior is inconsistent across devices; in iOS, the app places the image outside the infobox and gives a preview warning for unknown parameters.

What should have happened instead?:
The app should rely on the TemplateData documentation of each infobox and only insert valid parameters.

If no appropriate infobox parameters exist, the image should be added outside the infobox.

The app should provide a preview warning (same as iOS) when an invalid parameter is attempted.

iOS app behavior differs (does not attempt to insert into infobox).
