Working within Kompozer's split-view, going from a selection in the Design pane to the Code pane changes the font size in the code pane without respect to the Font settings in Kompozer's options panel.

Kompozer Split-View with Code pane selected, Font size changed to smaller monotype--Kompozer disregarded preferred Font Options
I am running Ubuntu 9.10 with Kompozer 0.8a4. Here is what is happening:
1. I have an HTML document open in Split Pane
2. I have clicked onto the Design pane to edit text inside the design pane
3. In the Code pane, the code associated with the text shows up the way I set in Options menu -> Font settings
4. I then click onto the Code pane and the code in the Code pane changes from my Font size (18pt Monotype) to the standard Kompozer font size
"View source" mod and code editor have different fonts definition, that's all. I don't see a real bug. This trouble doesn't affect the web page rendering.
Even if it doesn't affect web page rendering, it is annoying and makes it harder to work within Kompozer.
