I did create titles with the default transparent background in the original 
project, as you said. 

So, I implemented your recommendation and created a project with two titles, 
both with black backgrounds. In the track editor, I put one overlapping the 
other Video2 to Video3 and added a Dissolve transition. 

When I preview the rendered result in the Project Monitor, the second title 
increases opacity as but the first title's opacity does not change. It simply 
goes away at the end of the title clip. 

That's not what was happening before 0.9. If I did this before, the first title 
would lose opacity and the second title woudl gain opacity, simultaneously. 
Like a crossfade. Should be simple to understand, but that's not what I'm 
seeing. 

If I dissolve between two video clips, the result is a mutual crossfade you'd 
expect.

If I dissolve between a video and a title, the result is inconsistent. It 
seems to matter whether the title is in a track above or below the video. 
Sometimes there is a crossfade between the clips. Sometimes the video clip 
instantly has 100% opacity while the title clip's opacity gradually fades to 
0%. Sometimes the video clip fades in while the title clip remains at 100% 
until it cuts out.
