This fix required upgrading to 1.1.17, but it's not squashed with the upgrade, because that would complicate keeping the copyright-fixing commit separate from the upgrading commit. The new version of the plugin makes it so we can trigger a resize event, but it's backward incompatible with our old compose box code. A minor cleanup here is that we also don't trigger a resize right before hiding the compose box. (imported from commit 6b0cb9ccd2ddef919fd375a80cfca535b5b74c0f)
