Glyphs keeps thinking a smart glyph has been changed when it didn't

  1. Open
  2. Scroll down to horncomb and ogonekcomb. Note how the file is marked as being changed already.
  3. Save
  4. Scroll somewhere, e.g. the top.
  5. Scroll down to see that both glyphs are marked again for apparently having changed.

Both are smart glyphs.

This is somewhat annoying because it keeps triggering.
