Block mover controls hidden on full-width block

[dianeco]

Describe the bug
The block mover controls are hidden for all full-width blocks making impossible to move them.
This regression appears at least since Gutenberg 5.3 and therefore is in WordPress 5.2 Beta 1.

Looks like the HTML changed at some point?
In addition to the full-width movers being hidden behind the admin-sidebar, the align-wide movers are now vertical and on the side instead of horizontal above the block like they once were.

The CSS selector for full width is:

.editor-block-list__layout .editor-block-list__block[data-align="full"] > .editor-block-mover

I haven't check but I'm guessing it's still there.

It's missing the target now because .editor-block-mover isn't a direct descendent of [data-align="full"] or [data-align="wide"] anymore. It's wrapped in block-editor-block-list__block-edit now.

If the current HTML is correct than the CSS selector needs changed to something like this:

.editor-block-list__layout .editor-block-list__block[data-align="full"] > .block-editor-block-list__block-edit > .block-editor-block-mover

Is this HTML change legit? Should the CSS be adjusted? @kjellr @youknowriad
