Odd native scroller issue on iOS

So, after some more of Œtrying everything¹ it seems that it¹s the
scroller¹s rect rather than its contentRect that is causing problems. If I
pull the rect in far enough on both sides so that it doesn¹t overlap the
affected control but keep the contentRect large enough that it does cover
them then I can still scroll using the full width of the form and the
controls remain responsive because they are outside of the scroller¹s rect.
The problem is of course that the vertical scroll indicator appears at the
edge of the scroller rect rather than at the edge of the form /
contentRect meaning that I have to hide the scroller¹s vIndicator.
I think I better bug report this.
