==== Original task description ====
Steps to Reproduce:
- Unsure, maybe impossible. When I open my own newcomer homepage, the thumbnail image of https://hu.wikipedia.org/wiki/N%C3%A9metorsz%C3%A1g is `//upload.wikimedia.org/wikipedia/commons/thumb/2/26/EU-Germany.svg/47.558139534884px-EU-Germany.svg.png`, which is invalid (it looks like a thumbnail URL mixed up with a geocoordinate).
Actual Results:
- The thumbnail image for the Németország article doesn’t appear, its place is blank.
Expected Results:
- A thumbnail (or placeholder) appears, just like for the other four articles.
==== Proposed solution ====
Per @Etonkovidova's confirmation of the bug and notes in T245508#6778931, it seems like certain SVGs are not being rendered properly as the thumbnail.
For such images which are resulting in a "Cannot load the image" console error, can we instead show the placeholder thumbnail image (shown when an article has no image available)?
