KeyTips: a compact button's badge no longer covers its icon (#4497)
KeyTip badges cover compact button icons ## Summary Build: WordCraft v0.11.0 on Windows. When KeyTips are showing, the badge is painted on top of the button icon. On compact ribbon buttons the badge hides most of the glyph, so an icon-only command cannot be identified while choosing its letter. ## Geometry `widgets::small` allocates a 24×22 px button and paints a 17×17 icon centred at x=12. `keytips::badge` places a 15×15 badge at the control's top-left corner plus 2 px right and 1 px down. Relative to the button's top-left: - badge: x 2 to 17, y 1 to 16 - icon: x 3.5 to 20.5, y 2.5 to 19.5 - overlap: 13.5×13.5 px, about 63% of
