Responsive can cause problems with complex headers when hiding the first column

Hi there, sorry if this problem has already been reported, but couldn't find it here.

It looks like when using the responsive extension and having complex headers, hiding the first column can result in the header not being properly adjusted.

Live example: https://live.datatables.net/pavimila

Problem only seems to happen with the first column, at least with my data set, and it goes away when removing the responsive extension. Trying to make any other changes to the columns' visibility after the table is drawn also seems to fix it.
