 == Test Report

 === Environment
 * OS: macOS
 * Server: nginx
 * Localhost: Local
 * WordPress: 6.5.5, 6.6.1, and 6.6.2
 * PHP: 7.4.30
 * MySQL: 8.0.16

 === Steps to Reproduce or Test
 1. Go to Appearance > Editor.
 2. Open the Styles UI by clicking on the page and then the Styles icon in
 the top toolbar.
 3. Open the Layout UI.
 4. Change the Block Spacing to `0`.
 5. Navigate back to the Styles UI.
 6. Open Blocks > Paragraph.
 7. Scroll down to the Margin. Open the Set Custom Size. Set 200 in the
 text box.
 8. Save the custom styles.
 9. Go to Pages > Add New Page and add multiple paragraphs (e.g
 [https://loremipsum.io/generator?n=5&t=p 5 generic paragraphs] to copy and
 paste).
 10. Notice the paragraph spacing 🐞 Reported bug should occur here.
 11. Back in the Site Editor, change the Styles > Blocks > Paragraph margin
 to another number such as `60`.
 12. Refresh the Page editor. Notice the paragraph spacing. Did it change?
 🐞 Reported bug should occur here.

 Repea the tests on 6.5.5, 6.6.1, and 6.6.2 to note the differences.

 === Expected Results

 When reproducing the reported bug:
 - ❌ The paragraph spacing should not change from the default after
 setting its margin in the Site Editor Styles > Blocks > Paragraph UI.

 ==== Actual Results

 Results on 6.5.5, 6.6.1, and 6.6.2 were the same in my testing. The
 paragraph margin rendered as expected in the post and page editors.

 Step 9-10 CSS:

 {{{
 :root :where(p) {
   margin-top: 200px;
   margin-bottom: 200px;
 }
 }}}

 After changing it to 60, the CSS:

 {{{
 :root :where(p) {
   margin-top: 60px;
   margin-bottom: 60px;
 }
 }}}

 I was not able to reproduce the reported bug on 6.5.5, 6.6.1, or 6.6.2.
