For #11858, I reproduced the issue by running a local server behind
ngrok, _with the exact_ same path as the one in the website:
`https://server-url/images/permanent/mdm-migration-screenshot-768x180@2x.png`
I tried multiple combinations, but at the end, removing the `@` made the
trick. My guess is that's something to do with the markdown parser
library used by swiftDIalog.
I also removed a rogue `\` that was being displayed.
