Fix the bug with scroll area being too big (#169)

* Fix the bug with scroll area being too big

On the scroll event I translate header using "transform" property.
But on the update event, there's an issue when content shrinks,
but the header stays on the same position; it may cause the header
being farther to the right than the content.

This commit translates the header to the correct position and
forces browser to recompute scroll area, so you wouldn't
scroll past content and header.

* Fix the bug with scroll area being too big and update packages

* Fix eslint error
