Yes, and this is a known bug. Users who use MathJax rendering do not see 
an error when they do not use $ delimiters, but their equations are not 
visible to people using a different math renderer (like tth, which is 
the current default). And printing fails.
There are other issues related to the use of several math renderers. For 
instance in this case \widetilde is not recognized by tth. Currently it 
might be better for authors to use tth, or to try different renderers.
