Dropping a .md file into a note imports its text instead of attaching the file (since today's update)

Since updating the desktop app today, I can't attach markdown files to notes by drag and drop anymore.

What I do: Drag a .md file from Finder into a note, inside an expanded toggle block where I keep other attached markdown files. The green plus and the drop indicator line both appear in the right place.

What I expect: The file gets attached as a file block where I dropped it, the way it did before the update.

What happens: Nothing gets attached at the drop point. Instead, the full text of the markdown file gets added to the bottom of the note. I didn't notice at first and dropped the same file several times, so I ended up with several copies of a long document at the bottom of my note that I had to delete by hand.

What I've found:

The same file attaches normally if I zip it first.

It also attaches normally if I rename the extension (for example, .md to .mdfile).

So it looks like the new version handles the .md extension differently and imports the file instead of attaching it.
