Not related to this PR but would you like to do a small polish for UserPrompt?
~ 23-28 lines
```
        anchors {
            fill: parent
            bottomMargin: Theme.paddingLarge
        }

        contentHeight: contentColumn.height
```

Lines 38-42
```
            Item {
                id: promptContent
                width: dialog.width
                height: childrenRect.height
            }
```
With this fix url field of bookmark edit would scroll fully visible in landscape mode.
