Appearance button disappears when you click on a different item

Issue type

UI bug

Bug description

Selecting a different text object, when the Appearance subpanel is open, causes the Appearance button to disappear from the Properties panel.

Steps to reproduce

Note: This test was conducted on a laptop with a 15 inch screen.

1. Open the attached score.
   disappearing_button.zip
2. Click on a Fingering
3. Click on the Appearance button (Properties panel)
4. With the Appearance subpanel still open, click on a different fingering

Actual behaviour: The Appearance button disappears from the properties panel.
Expected behaviour: Appearance button should be visible at all times. This allows the user to close the subpanel with a mouse click and keep the text objects selected.

5. Now press Esc to close the Appearance subpanel.

Actual behaviour: The subpanel closes and any previously-selected text objects are unselected. The user has to reselect the text items in order to continue using the Properties panel.
Expected behaviour: Only the subpanel should close leaving the text-object selection intact. The user can continue to use the Properties panel without having to reselect anything.
