In site title block, background color adding padding in Full Site Editing Editor.

[Smit2808]

Description

In FSE(Full Site Editing) editor side, when we give background color to the site title block. Then it is adding padding: 1.25em 2.375em. I have checked in inspector tools and found out that this CSS is affecting.

h1.has-background, h2.has-background, h3.has-background, h4.has-background, h5.has-background, h6.has-background {
    padding: 1.25em 2.375em; 
}

And also found out that this CSS is only affecting in editor side only. In front it is working fine.

Step-by-step reproduction instructions

1. Open FSE.
2. Select the site title block in the nav menu.
3. Add the background color and you can see some padding will be added with background color
