abbr title in th not picked up for column toggle

[DerGuteWolf]

According to the documentation when a th of a column toggle table contains an abbr with titile, this title should be used in the column toggle. This simple does not happen.

Thanks for reporting the issue. The behaviour does indeed not match the documentation. We will look into this.
