For example, RenderView::subtreeSelectionBounds does a 'enclosingBoundingBox', and InlineTextBox::localSelectionRect does a 'enclosingIntRect' instead of 'snapRectToDevicePixelsWithWritingDirection' (which is what happens in the painting code). This means that FrameSnapshotting::snapshotSelection often returns a snapshot that doesn't precisely match the blue highlight. This also breaks TextIndicator's BounceAndCrossfade animation, which depends on that being true. 1050075 1 webkit-bug-importer 2014-11-20 00:37:50 -0800 <rdar://problem/19041871>
