Steps to reproduce:
1.Open a new page with VE
2.Go to Insert>Formula
3.Insert "\pi"
Observe that, nothing appears on CE. But if you save the page or review your changes , you will see it actually got added in the page .
If you reopen the page after saving, and try again adding the same math expression it will appear immediately.
But if you try adding a different math expression or modify the existing math function , say for example: make "\pi" to "\sqrt\pi", it wont render on CE again.
