Hi,

this CL can fix this issue #146, only one line involved

@evgenykuzyakov could you please take a review for this CL

I think the if condition should be like the one below, otherwise falsy values will pass through:
!element || typeof element !== "string"

do you have any actual falsy value for a example? it does not exists in my thread, however if there were, it passes through the previous logic as how it had been processed before.
