We need to merge #8276 first to ensure all deprecation scheduled for removal for 3.4 are cleaned up.

Based on discussion in Slack (here: https://wordpress.slack.com/archives/C02QB2JS7/p1532974347000244) I snuck in #8314 as a fix for the Classic Block toolbar looking broken. Here's something you can use for the changelog.

• Fix issue where Classic Block toolbar would look detached from the block itself.
