qsTr function is not present by default when creating new state with Qt Quick Designer

Steps to reproduce:

1. Open the attached project.
2. Open qsTrChangeIssue.qml
3. Go to Design mode.
4. Create new state in states preview tab.
5. Select text component.
6. See that qsTr icon is switched off (while the basic state has it on)
7. Enter text in text property.
6. See that text goes back to text from basic state.

Two things that are worth to notice:
1.When you go back to Edit mode and Redo changes, then you'll see that new text has been entered but automatically replaced with text from basic state.
2. When you select icon of qsTr in Design mode then text doesn't go back to basic state's.

In a larger context one experiences lack of default qsTr function in text property when creating a new state in Design mode.

Also the state Text field doesn't seem to update correctly.
