Cannot use css has adjacent sibling combinator matching rules in rewrite rules to remove dom elements

[NavyD]

In this feed , I need to select the h2 element adjacent to p to remove, the css rule is h2:has(+p), and the following is part of the html content:

<h2>S3 Storage (Long-term availability not guaranteed)</h2>
<p>https://release.dreamacro.workers.dev/</p>
<h2>Changelog</h2>
<h3>2023.03.18</h3>
<ul>

    <li>fix <code>auto-detect-interface</code> TUN loopback on Windows in some cases @Kr328</li>
</ul>

I try to fill in remove("h2:has(+p)") directly in rewrite rules, but it doesn't seem to have any effect.

I'm also having this issue, but for me its when trying to remove subscribe now links from substacks. I tried adding remove("p:has(a[href$='.substack.com/subscribe?'])") but it doesn't work, and I believe its due to :has not being implemented.

This feature does not appear to be supported by GoQuery/Cascadia librairies.

To answer the first comment, you might be able to achieve what you want using h2:first-of-type.
