@anth@a.9srv.net that doesn’t work because you need encode that URL, like so http://a.9srv.net/tw.txt#:~:text=2024%2D10%2D08-,2024%2D10%2D23T18%3A59%3A49%2D07%3A00

The specific syntax must (should) be followed as well: https://wicg.github.io/scroll-to-text-fragment/#syntax

The text parameters are percent-decoded before matching. Dash (-), ampersand (&), and comma (,) characters in text parameters are percent-encoded to avoid being interpreted as part of the text directive syntax.
