I haven't tested this, but couldn't this trigger a "block content has changed" warning/error on existing sites? Or wait, rather wouldn't the extra units be coming back as they are still part of the block attributes?

Hi

This does not cause any validation errors for the block markup in the editor, but I would prefer for it to be reverted:

1) The values in the block comment and the style attribute needs to match. It did not cause a block validation this time, but if it had been a different block attribute like class name or tag name, the mismatch would have caused an error.

2) The block control does not accept unitless values. If we would solve the mismatch and remove the unit from both the comment and the markup, then the block control
in the editor would not display the correct value. I believe this may be why the unit is not removed by the editor when it prepares the CSS.

@SergeyBiryukov can you address the comment from Carolina?

I browsed the code, and it looks like 0px or 0rem in TwentyTwo theme all over the place, but it is only there. And here is a good point that block attributes and actual block needs to be match. 🤔

This changeset reverts [55898] which removed redundant px units in a few inline styles, because 1) The values in the block comment and the style
attribute needs to match ; 2) The block control does not accept unitless values.

Props TobiasBg, poena, oglekler.
