Text wrapping and image alignment for images in Knowledge Base articles?

I see that images in content blocks can now be aligned and formatted with text wrapping; is there a reason that this isn't available in the ZenDesk Guide articles editor? I can apply styling to the images in the raw code and have it function in the editor, but when I publish the article, this styling disappears.

In published format: 

I found this Community Post that seems to be talking about a similar issue from a couple months ago, but according to the post, this was resolved.

Any help with this would be appreciated! :)
