Assertion fails in Cody even though the assertion passes in MATLAB R2014b. Does any one know why?

Hi. The assertion could only have passed outside of Cody if the wrong "correct solution" were specified for comparison, and this would happen if you copy the HTML-rendered text — due to a kind of bug in the way the solution vector is displayed on the Cody webpage (better: copy from the HTML _source code_). -----
The correct solution has delimiters (here shown as ^ for clarity) as in 'this^one^^has^ ^some tricky^stuff', whereas your code produces 'this^one^has^some tricky^stuff', so you don't get the correct result between "one" and "has", nor between "has" and "some".

Test	Status	Code Input and Output
1	Pass	x = {'hello', 'basic', 'test', 'case'}; y_correct = 'hello basic test case'; assert(isequal(cellstr_joiner(x, ' '),y_correct))
2	Fail	x = {'this', 'one', '', 'has', ' ', 'some tricky', 'stuff'}; y_correct = 'this one has some tricky stuff'; assert(isequal(cellstr_joiner(x, ' '),y_correct)) Assertion failed.
3	Pass	x = {'delimiters', 'are', 'not', 'always', 'spaces'}; y_correct = 'delimiters?are?not?always?spaces'; assert(isequal(cellstr_joiner(x, '?'),y_correct))
