Description

After updating uBlock Origin Lite for Safari to version 2026.504.1635, all cosmetic filters using :has-text() stopped working.

This does not seem to be limited to X/Twitter. I tested multiple websites, and it looks like no :has-text() filter works anymore on any site.

Basic cosmetic filters still work, but procedural cosmetic filters using :has-text() do not apply.

Example filter
x.com##article:has-text(/english dub/i)

This used to hide matching posts/tweets, but after the latest update it no longer works.

and filters on other websites, but the result is the same.

What still works

Basic cosmetic filters

I also noticed that some regular ID-based cosmetic filters do not work on X.com either.

Example element selector:
x.com###id__t1suwd8y2hs

it does not hide the matching element.

A specific URL where the issue occurs.

https://x.com/animeupdates

https://old.reddit.com/r/Piracy/

Steps to Reproduce

1. Install/update uBlock Origin Lite for Safari to version 2026.504.1635
2. Add this custom filter: x.com##article:has-text(/english dub/i)
3. Open https://x.com
4. Find a post containing “english dub”
5. The post is not hidden

Expected behavior

Posts/articles containing the matching text should be hidden.

Actual behavior

The filter does nothing. The matching post remains visible.
