Images do not work for markdown files - neither shown, nor opened when clicked (in read mode; okay in edit mode)

If one opens a md file in the android client the images are not shown but just a placeholder.

First expectation would be to show the images, as they are shown in the webclient, if the user has the permissions to view them.

When clicking on the placeholder the android client does not open the image either but asks the user to log-in via the webclient.

Expectation would be that at least when clicking on the placeholder the image should be opened as if one would have selected it from the file list.

The same issue was reported on the nextcloud forums:
