Martin Robinson 29fc878e15 compositor: Do not allow script to scroll beyond node boundaries (#37412) ...

The compositor was accepting scroll offsets from the ScriptThread
without checking their boundaries. In some cases this could cause a
temporary discrepancy with the rendered scroll offset. This change makes
it so that all offset updates for scroll ayers in the compositor do not
scroll past the scroll boundaries of the node.

Testing: Two new tests pass with this change:
 - `/css/css-position/sticky/position-sticky-left-003.html`
 -  `/css/css-position/sticky/position-sticky-top-003.html`
