Block mover not actionable when the theme content is left aligned

[afercia]

Noticed in Twenty Nineteen, see WordPress/twentynineteen#665 and WordPress/twentynineteen#614

The "block mover" position in Gutenberg makes the assumption the post content is centered.

Normally, the block mover is positioned vertically on the left of the block. Instead, when a block is set to "wide" or "full" alignment, the block mover is positioned horizontally "inline" with the block toolbar.

With a "full" alignment, there is space on the left for the block mover unless the theme changes the toolbar position: Twenty Nineteen does change the toolbar position and this is tracked in WordPress/twentynineteen#665. Themes should just not change the toolbar position: problem solved.

However, the real problem in Gutenberg is with the "wide" alignment. When the post content is left aligned, there's really no space to display the block mover:

I'd tend to think this should be better handled in Gutenberg itself, as mentioned at some point in WordPress/twentynineteen#614

I think that issue is fixed. I can access the movers properly in wide aligned images in TwentyNineteen.
