VS Code currently does not let us know when the buffer has been modified, so we don't know that these breakpoints shouldn't be bound to the now-stale source information. VS Code issue #8077 should enable detecting this, then we can disable stale breakpoints.

Fix should be available in the next release to address breakpoints binding to the wrong location after saving. We don't get any information from VS Code about a modified buffer currently, I've filed VS Code issue #9823 for this.
