Deployment: "Select a release to deploy" view can pick up build results from wrong branch

When performing a deployment linked from a build plan that is configured to use a custom branch, the "Select a release to deploy" option lists build results from the main branch instead of the custom branch:

The workaround is simply to unselect then reselect the plan branch, as shown in this video: http://screencast.com/t/7DMUuXsJB

If you don't know about this, it's pretty easy to accidentally deploy the wrong artifacts.

Encountered on ebiac running 5.3-rc1 build 4101 on this plan.
