    We occasionally get error emails when web crawlers load datagrids with
    
poorly-formatted query parameters. Our own links will never try to load
    
?sort=,, but crawlers sometimes do. This change fixes it to properly
    
handle the situation where we have a non-empty sort string (",") but do
    
have empty sort parameters.
    
 
    

    





  

    
 
 
    
  
    Loaded a dashboard with ?sort=, and saw that the page loaded instead
    
of creating a crash.

      Fix crashes when loading datagrids with ?sort=,
      
    We occasionally get error emails when web crawlers load datagrids with
poorly-formatted query parameters. Our own links will never try to load
`?sort=,`, but crawlers sometimes do. This change fixes it to properly
handle the situation where we have a non-empty sort string (",") but do
have empty sort parameters.

Testing Done:
Loaded a dashboard with `?sort=,` and saw that the page loaded instead
of creating a crash.
