Compound clip only shows default background when title background is used
I've created a title in Motion. When I use the title in Final Cut Pro X, all is well until I make a compound clip. The compound clip in the timeline now shows the title's default background.
To reproduce the effect, create a new title project in Motion. Leave everything at the default settings, but enable the title background. Save the title. In FCPX, put the title on a clip in the timeline. Observe that the clip in the timeline is drawn as a film strip, showing the content of the clip. Now select the clip and the title, and turn it into a compound clip. Observe that in the timeline you can no longer see the content of the clip. Rather, the film strip shows the default title background.
Is there anything I can do to get the film strip to show the content on the compound clip?
