When having the following structure:

FocusScope {
Button{
id: button1
}

FocusScope {
activeFocusOnTab: true
FocusScope {
Button {
id: button2
}

Button {
id: button3
}
...

Navigating around the ui with the Tab key, gives the following order:

button1, button2, button3, button1, button3, button1, button3...

with no way to navigate back to button2 without using Shift+Tab

if the focusScope has activeFocusOnTab: false, the navigation order is as expected

This is particularly a problem with QtQuickControls1, where the ScrollView component has exactly this structure
