Changing footnote numbering font in footnote

Hello, I am trying to change the size of the footnote numbering in the footnote itself. Changing ‘Footnote Characters’ changes the font itself, changing ‘Footnote Anchor’ changes the numbering in the text, but not in the footnote.

I am afraid you cannot change the size of the footnote number in the foot note area (= in front of the footnote text).

I made a test in LbiO 4.3.5.2 on XP.

Thank you! Should this be reported as a bug?
