After updating to version 5.3.0, all the sections that are after an Accordion Addon are left without margins and without paddings, and the cause is the content of the Accordion addon (Text Block), this problem does not only happen with existing addons but also when you add a new accordion.
I have not had time to review the code as on previous occasions and tell you where the error is, but the problem seems to be that there is a conflict between the new version of the addon with the JSON that has been added and continues adding the addon when dragging, because when the Text Block addon is removed from each accordion and a new Text Block addon is added again it works perfectly. But we can't start editing hundreds of thousands of pages just for this, so please fix that bug in the next version.
Reproduce the bug:
Create 2 or 3 sections, in the first add the accordion addon, in the second and in the third add any addon, either in the backend or frontend editor, then see the page in the public part and you will see that the sections after the accordion They do not have margins or padding, if you see in the console the properties do not exist.
