Twenty Seventeen: List block padding issue in editor side

[kajalgohel]

In Twenty Seventeen Theme, when we add List block in editor side and choose background color for that block, We can see that there is padding issue in editor side but it is working properly in front side.

Steps to replicate:
1: Activate the Twenty Seventeen Theme
2: Add List block
3: Enter some data
4: Choose background color
5: View the page/post at editor side
6: Save page/post
7: View the page/post at front side

For better understanding I provide video attachment link.
