STEPS TO REPRODUCE
1. Open Kmail composer with the global menu enabled
2. click on the hamburger menu
Text is truncated correctly and not just cut
Linux/KDE Plasma: openSUSE tumbleweed (but using kdesrc-build)
KDE Plasma Version: master
KDE Frameworks Version: master
Qt Version: 5.15.2
This bug happens in any QMenu that adds a section (QMenu::addSection(text)) with text that is very very long.
The bug is encountered in KHamburgerMenu when a global menu bar is used because in that case no "Show Menubar" action is visible which reduces the overall width of this menu so it is narrower than the "<amount> Menu Bar Exclusive Actions" section text.
I think the correct fix for this isn't in KConfigWidgets since this is a general problem on how section text sometimes doesn't fit in the QMenu. Maybe it should be fixed in the style.
>Text is truncated correctly and not just cut
Alternatively the width of the QMenu should be wider so everything fits.
