Slash post data when receive a subscription update

[chandrapatel]

Description of the Change

Post data not slashed when receive a subscription update from remote site. So, some post content like [latex] shortcode from MathJax-LaTeX plugin contains slash \ which get removed when updating post.

Original Post

[latex]\delta Z(t)| \approx e^{\lambda t} |\delta (Z(0))|[/latex]

After remote post updated

[latex]delta Z(t)| approx e^{lambda t} |delta (Z(0))|[/latex]

How to test the Change

• No need to install MathJax-LaTeX plugin on source and destination site.
• Add [latex]\delta Z(t)| \approx e^{\lambda t} |\delta (Z(0))|[/latex] shortcode to post on source site.
• Distribute post to external site.
• [latex] shortcode will migrate correctly on external site because if post is not distributed previously then it distributes using WP Core REST-API and it slash post data.
• Add tets content to post on original site but keep the shortcode same.
• External site post will be updated and shortcode will be updated like [latex]delta Z(t)| approx e^{lambda t} |delta (Z(0))|[/latex] where \ removed so shortcode does not render correctly by MathJax-LaTeX plugin.

@chandrapatel I'm having trouble reproducing this, sorry.

I've tested with both the classic and block editors using an external site, are you pushing or pulling to distribute?

@peterwilsoncc I'm pushing to external site. Did you update the post on the original site after it was distributed for the first time? Because this issue happens when distributed post updated.
