Issue description

I'm unable to search in Godot documentation using the usual Find UI that's built-in to VSC.

I am able to open and type into it with CTRL + F. However, even if I type words that I can clearly see are present in the webview, it returns no results.

I'd expect to be able to search for keywords in the documentation.

Steps to reproduce

1. Invoke the Godot Tools: List Godot classes command.
2. Search something like AnimationPlayer.
3. Do CTRL + F. (This should open in the built-in Find UI.)
4. In the Find UI, search something like animation.
5. Observe that it has no results.
