[5.5.0]: Live preview with Matrix Blocks

[rgauthier4c4]

What happened?

Description

I had this issue (#15713) with the live preview and I've update my project to the version 5.5.0 to test the new features.

Changing the status of a block refresh the live preview (without a draft). I understand that the status is linked to the entry and not the draft. But if I am editing an existing block, the live preview isn't using the drafted version of the content.

And i've see another bug in the same flow. If you create a Matrix entry and leave it as a draft and open the live preview. If you drag the order of another block, the drafted entry is appearing in the live preview, but you can't open the panel to edit it because the draft was saved and publish. If you close the preview, your block is now active.

Hi, thanks for reporting!

Live Preview won’t update as you type within the nested entry slideout, but it will update once you press Save.
Thanks to #16002, as of 5.5.0, changes made to the nested entries are not automatically published when saved - they’re part of the owner’s draft, and only once the owner is saved (draft is applied) will those changes get published, too.

We’ll look into the other 2 issues you mentioned!
