sorting by field while table has unsaved changes causes page to crash


I reproduced similar results.  Open Chrome Developer tools and take a look at the JavaScript console output.  Here’s what I get:

That would be a bug.  We “grey out” the sort arrows,  but have not disabled the click action. 

Has this been addressed? I’m seeing the same behavior with toggle filters. They are “greyed out,” but if I click on them anyway, they break the page.
