Fill Format Mode (in the Styles and Formatting window) works for Graphics Styles
but not for Presentation Styles.

Reproducible as follows:
 1. Create a new empty Impress presentation
 2. Show Styles and Formatting window (F11)
 3. Choose Outline 1
 4. Click Fill Format Mode
 5. Fill Format Mode is now turned on but the mouse cursor does not change
correspondingly but remains the normal arrow cursor

Applying presentation styles does not seem to work at all:
 1. Create a new slide with some text in it
 2. Format the text somehow (WITHOUT using styles but manually selecting the
text and changing eg. the font size from the toolbar)
 3. Try selecting the text and double-clicking Outline 1 in Styles and
Formatting -> nothing happens
 4. Try selecting Outline 1, turning Fill Format Mode on and clicking the text
-> nothing happens
