This patch should make the detection of whether we should reframe in UpdateContainingBlock exact. It should have no behavior change, but sometimes reframing can confuse event handling code or what not. We don't have a reduced test-case for the event handling regression this fixes, but I added a test to ensure we don't uselessly reframe in this case that fails without this patch and passes with.
