Fix inline focus ring paint invalidation on continuation change

An inline element's focus ring encloses its block and inline
continuations. The previous method handled invalidation of
display item client only, not rectangles covering the changed
inlines.

Now call setMayNeedPaintInvalidation() on the inline whose block
continuations are marked needsPaintOffsetAndVisualRectUpdate().

Also noticed a focus ring painting bug ( crbug.com/703403 ) and added
a test case. Will fix later.
