Description:
The check marks in the Format->Text->[Superscript, Subscript] and Format->Spacing->[Line Spacing 1, Line Spacing 1.5, Line Spacing 2] menu options persist after they have been used to remove the property. They correctly change the property on the selected text (as does the toolbar and sidebar buttons), but the check mark isn't removed. I can get all the options to have check marks even though they should be exclusive. It seems like the state of the selected text is not queried or properly communicated to the function that sets up the menu entries. It persists when selecting text (or placing the type bar) into several different text boxes. Placing the type bar on normal text, then invoking the menu "resets" the check marks. Double clicking in a box with subscript text and invoking the menu seems to "set" the subscript value. Double clicking on other text boxes with unmodified text will now show the incorrect check mark. However, double clicking in a box with subscript text and NOT invoking the menu, then double clicking in a box with unmodified text shows the correct cleared checkbox.

The same behavior happens to the Format->Spacing->Line Spacing settings. 

This only applies to text placed in a 'text box' or other draw object added from the Basic Shapes toolbar button. When working with regular text, the check mark behavior is correct. It is also restricted to Writer.

Steps to Reproduce:
1. Open Writer, new file
2. Create a text box or basic shape, add text.
3. Create a text box, add text, subscript it.
4. Check the Format menu (Subscript is checked correctly)
5. Double click in the normal text box
6. Check the Format menu (Subscript is checked incorrectly)
7. Select subscripted text, and use Format menu to change it to superscript
8. Double click in the normal text box
9. Check the Format menu (Subscript and Subscript are checked incorrectly)
10. Type in some standard text
11. Check the Format menu (both unchecked correctly)
12. Double click in the normal text box
13. Check the Format menu (both unchecked correctly)
14. Double click in the now superscripted text box
15. Check the Format menu (Subscript is checked correctly)
