I can confirm the bug and that this fixes it. However, you're porting to use the QQC2 Combobox even though https://bugs.kde.org/show_bug.cgi?id=403153 isn't fixed yet. As a result, the pop-up looks like this a lot of the time: F7768289: Screenshot_20191117_082250.png <https://phabricator.kde.org/F7768289> I think we'll need to redouble our efforts to fix that bug, or else work around it by setting a minimum width on the combobox here (not ideal, but maybe better than nothing?)
