Clipping webpages saves print version?

I am using the web clipper add-on in Firefox to clip websites as HTML to my DEVONThink Inbox. That works. But when I go back into the Inbox and click on the entry that was just added to the inbox, I get the print-preview window. See screenshot.

How can I prevent this?

You can’t and it’s site-specific. It’s due to a regression we have fixed for the next maintenance release.

Right now only by using Markdown, rich text, formatted note or PDF.
