Fixed post content rendering issue on latest post block

[sabbir1991]

What?

#69427

In this PR, I fixed the post content rendering on the latest-posts block when the displayPostContent setting is enabled.

Why?

The issue was on the latest-posts block, the post content rendered with block comments, and those block contents were not parsed. In this fix, I used the filter to parse the content.

Testing Instructions

• Create a few posts.
• Insert a latest posts block.
• Save and view the HTML of the latest posts block on the front of the site.

Screenshots or screencast

Check the inspect element.

I have 10 posts on my test installation. When I try to open my test post that has the latest posts block, I am getting this error:
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes)

Hi @carolinan. I tested with 12 posts in the frontend and backend but can't reproduce any of the errors that you mentioned. Is that error showing on the front end or back end?

[carolinan]

Both
Did you set the latest posts block to use the post content, not the excerpt?

[sabbir1991]

Yes, I have set post content with Full post settings.

[carolinan]

I will try again on a different installation, perhaps on a Mac, but I won't have time today.

I have tried again and the same error shows. Try adding more than one latest posts block to the same post. I think there is an infinite loop, I am not sure how else this error would happen.

Just adding a note here that it also partially fixes this issue: #69517. It continues broken on the editor though.

I tested #61477, and this PR also fixes this issue in the frontend.
