PDF - Full width preview in notes

I attach PDFs into notes.
Some allow for a full width view and some not.
Was wandering what causes this inconsistency between PDFs…

If a PDF is very large, we don’t show full width, because it was very expensive to load the file.

Do you see if the ones not showing are very large?

We could perhaps look into this again. Perhaps changes we have made in the meantime will have helped.
