Header actions text is cut off

See the attached screenshot.

- Expected: actions drop-down expands to fit the contained text. Alternatively, the documentation warns about a maximum character size. Alternatively, text is ellipsized.
- Actual: text longer than a given size (which?) is cut off

This will affect translations for system and core apps in particular, where the English text might fit, but translations that are longer will be cut off.

It corresponds to header actions for the following code snippet:

            head.actions: [
                Action {
                    text: i18n.tr("Settings")
                    iconName: "settings"
                    onTriggered: pageStack.push(settingsPage)
                },
                Action {
                    objectName: "hidepanelaction"
                    iconName: "edit-clear"
                    text: i18n.tr("Hide all key panels")
                    onTriggered: pgTerm.showExtraPanel(0)
                },
                Action {
                    objectName: "controlkeysaction"
                    text: i18n.tr("Show control keys panel")
                    onTriggered: pgTerm.showExtraPanel(1)
                },
                Action {
                    objectName: "functionkeysaction"
                    text: i18n.tr("Show function keys panel")
                    onTriggered: pgTerm.showExtraPanel(2)
                },
                Action {
                    objectName: "textkeysaction"
                    text: i18n.tr("Show arrow keys panel")
                    onTriggered: pgTerm.showExtraPanel(3)
                }
            ]
        }
