To Reproduce

Easiest to reproduce using the Testify samples.

If you load the Testify project, there are multiple baseline files with the same name. The Flix and the Paparazzi tests are all the same. Many are named "default.png" with the class name prefixed. In those cases, "go to image" can select the wrong one.
