Scrollbar hidden due to frozen columns

First of all , Thank you for this awesome library.

Currently, when I am using it for frozen columns, then the scrollbar is hidden under the frozen columns. When I have a huge number of columns, then it is getting completely hidden. Is there any way to avoid this or show the scrollbar fully ?

Here is the screenshot:

It can be observed in the examples page
