Function inlineSectionExtra

switch/source/SettingsScreen.cpp:147–152

Vertical space the section label of a NON-first row reserves above its rect. The very first drawn row always reserves labelSlotH() unconditionally (a sticky header slot), so its space never depends on whether it happens to carry a section — that constant top slot is what keeps scrolling from jumping when a group's header row scrolls off.

    // carry a section — that constant top slot is what keeps scrolling from
    // jumping when a group's header row scrolls off.
    int inlineSectionExtra(const std::string& section, const std::string& prevSection)
    {
        if (section.empty() || section == prevSection)
            return 0;
        return SECTION_GAP_ABOVE + labelSlotH();
    }

    // read in memory order (little-endian ARM), so the low byte is the first
