I have changed my preferred font for inspector comments from the default to another one. This works for my new notes, as expected.
However, I have some inspector comments created with the previous default font. I expected that right-clicking on one of them and selecting “Convert to Default Formatting” would change it to the new font. And it does, but only visually for a while.
But if a move to another document and later return to where I was, the comment still contains the previous font.
I suspect it might be a bug.
