Table data duplicates when multiple tbody elements present

[kentosi]

It seems that when there are multiple

elements the sorting completely breaks. It ends up duplicating the entire tables contents.

Note that multiple

blocks is valid HTML.

I've reproduced the error here: https://jsfiddle.net/KENTOSI/caqtdkfx/
