Ghost Issue #16685

The following image was added to this page using markdown. Note that it is left-aligned, and it does not show a caption. I would expect it to be center-aligned and show the caption 'Markdown Image'.

The markdown code for this image looks like this:

![Markdown Image](

Markdown Image

The next image was added as an image block. Note that it is center-aligned and shows the caption 'Non-markdown Image'
