Reproduction instructions: 1. Insert a comment on some cell, with text "foo" 2. Insert a comment on another cell, with text "bar" 3. On the menus, toggle View > Comments 4. Enter the "foo" comment (e.g. by double-clicking its text) and select all text 5. Reduce font size (e.g. from 10pt to 7pt) 6. Enter the "bar" comment (e.g. by double-clicking its text) and select all text 7. Reduce font size (e.g. from 10pt to 7pt) 10. Select the "foo" comment 11. Press "Clone Formatting" 12. Select the "bar" comment Expected result: No change to the format of the "bar" comment or its text. Actual result: Font size in the "bar" comment reverts to original (e.g. 10 instead of 7) Q: "But why is this a bug? Haven't we just applied some default font size of comment boxes, to the "bar" comment? A: If there is such an implicit CS in boxes, then it should be editable - both as a named format generally, as DF via Format > Character... when selecting a comment, and in the Properties sidebar deck; but none of these are enabled for comment boxes (the Properties deck is enabled, but doesn't have anything regarding font size, typeface etc.)
