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.
