Comment (by kjellr):

 > The floats aren't working well, though, and I think it's a regression of
 a previous fix that brought us this rule:

 Good catch. I think the `initial` approach is probably the simplest, and I
 don't think it'll cause any issues. I'd rather avoid targeting `.is-root-
 container`, just because I think targeting editor-specific classes has
 made this file a lot more prone to breaking than it should be.

 I've attached another patch. This one fixes that issue, but it does not
 push the right-aligned items far off to the right of the text column. I
 think that's fine for now, and it can be fixed in a followup PR. For some
 reason, I also had to add left and right margins (I think the theme
 previously relied on those to be provided by Gutenberg, but maybe they are
 not now?). In any case, here's how that looks now:

 This patch also fixes wide alignments inside of full-width group blocks.
 We should test (both in the current and plugin versions of Gutenberg) with
 a variety of different layouts to verify that this works well now.
