Validation notices on empty support references

[mandolyte]

From CV app, selecting Russian and Titus. The line in question has no support reference value.

I think it's because the SupportReference might be whitespace. Ah, line 77 contains a zero-width space only, and line 92 the same. Very hard for users to see or fix with existing tools. I think I've fixed it, but I don't have an easy way to setup an identical test.
