Emacs freeze when searching on the file.

[zer09]

Description

Probably related to issue #9220 and #9887.

The problem is that using / for searching emacs freeze. And the subject
file has just 500 line of html tags.

Just experience this when using the all-the-icons theme for the mode-line.
And adding the (spaceline-all-the-icons--setup-anzu) to show the anzu icon.
But removing the (spaceline-all-the-icons--setup-anzu) fix the issue.

I dont know if it is a upstream issue. Please tell me if I should open an issue
to https://github.com/domtronn/spaceline-all-the-icons.el.

Reproduction guide 🪲

• Start Emacs with the (spaceline-all-the-icons--setup-anzu) on the config.
• Open a file.
• Then start searching using the /.

Observed behaviour: 👀 💔
Emacs freeze and need to manually kill.

Expected behaviour: ❤️ 😄
Emacs should not freeze and highlight all the result.

Now on the latest commit, emacs will freeze even anzu is not enabled.

I would still report this upstream since it still seems tied to that package.
