Bug description
Pasting a link from tradera.com, e.g. https://www.tradera.com/item/342580/730777034/leica-39-mm-uv-filter does not include the social media preview image with the link. It works for other webpages.
This link tester shows the image: https://socialsharepreview.com/?url=https%3A%2F%2Fwww.tradera.com%2Fitem%2F342580%2F730777034%2Fleica-39-mm-uv-filter
If I set up my own HTML page with og:image, the image is shown in signal and on the test page: https://www.lysator.liu.se/~axl/tmp/og_image.html

I can see this issue both when sending from Android and Signal desktop on Linux (I have the snap though).

Research direction
Reproduce the missing preview image in Signal Android using the Tradera URL from the report, comparing it with the supplied HTML page and socialsharepreview.com result. Trace the Android link-preview handling from that reproduction; done means the og:image appears for the reported URL on Android and the existing desktop behavior remains unaffected.
