Add some standard padding inside the annotation comment popup note text field
Something that has annoyed me for many years is that the note contents look a little bit "broken" visually due to the lack of padding inside the text view; the letters are flush against the colored border of the note, as you can see, which feels cramped and unnatural (especially when you're used to GNOME's standard multiples-of-6px spacing from the HIG):
What I would propose instead is this:
It would probably be a one-liner fix. This screenshot was achieved simply by using the GtkInspector and setting the GtkTextview widget (named "view"), inside "EvAnnotationWindow", to have the "border-width" property set to 6
(instead of being undefined).
