Steps to reproduce the problem:
1. I have a JavaScript file called "index.html.test.js" which Workspaces 2.0 will not map to the network version.
2. *Breakpoints* set on the local version *will* work on the network version. So when one is hit, the network version is opened and I can edit it (but changes do not save)
3. If I *rename* the file (to index.html.xxx.js), and change callers to reference that, it works.
4. If I *rename* the file back to index.html.test.js, it again does not work.
5. The ".test.js" part is not the problem; I have other files named ".test.js" that *do* work.

What is the expected behavior?
This file should work the same as others
