Hovering on Padding/Margin control creates undo level

[Mamaduka]

When I hover over on Padding or Marging control, it creates "undo level" in the editor.

I can see EDIT_ENTITY_RECORD in Redux logs, triggered by onChangeShowVisualizer.

How to reproduce

1. Add a Group block to a post.
2. Open the "Dimensions" panel and hove over padding control.
3. New "undo level" is created.

Tested with TT2, Gutenberg trunk, and WP 5.9-beta4.

Thanks for the ping @Mamaduka.

I think this might be a duplicate of #36418.

There are some open PRs relating to this problem already.

• Use state for dimensions visualizers #33560
• Dimensions panel: remove BoxControl Visualizer callbacks #36587

As you note, this issue is due to the box control visualizers storing its data within the block attributes. Rather than duplicate or fork the discussion, I'd suggest we close this issue and continue it on #36418 or the PR most likely to proceed (#33560).

Thank you, @aaronrobertshaw. The #33560 looks like a good candidate.
