ScrollView has a flag to prohibit scrolling.  Mac has a setter for this in
WebView.mm, though I don't know what triggers it.

Unfortunately, it doesn't look to me like all codepaths check this.  It is
checked in setScrollPosition(), which is used in programmatic scrolling, pan
scrolling and (right now) wheel scrolling, and it is (perhaps wrongly?) checked
in updateScrollbars(), which is called by a number of different setup functions
like setUseFixedLayout(), setContentSize(), etc.  But it is not checked in
scroll(), which is used for keyboard scrolling and (in the future) wheel
scrolling.

More info on what this is used for would be helpful.
