Disable scrolling behavior for collapsing toolbar 

We intended to make subsetting pages disable the scrolling behavior
within the collapsing toolbar area. The collapsing toolbar is still
able to be expanded/collapsed depending on the content of page.

Fix: 191614437
Fix: 189003332
Test: manual test
