Both tabSetEnableClose and enableClose in tabset do not work

[JingLiNaomi]

Hi,

I am trying to add close icon to tabset, when global tabSetEnableTabStrip is false, but both tabSetEnableClose and enableClose in tabset do not work. Please see my code below:

Am I using it in wrong way? Thanks

Yes you are right, that is not implemented, I've removed it from the code/readme
