Different behavior of image tag in mac and iOS App

The image tag ![Innenraum](http://www.url.de//DSCFxxxx.jpg) to a picture in the internet is correctly displayed in the mac app of Joplin.
The same tag in the iOS App of Joplin displays only the “ALT attribute” without showing the image itself.

Is this a feature or a bug?

If this is the case, it looks like a bug. Maybe you want to open a github issue for it.
