**Describe the bug**

It looks like eaf-browser is unable to generate a webpage.

**To Reproduce**

`M-x eaf-open-browser RET duckduckgo.com RET` and nothing happens.

**Expected behavior**

A webpage should be displayed.

**Versions (please complete the following info):**

- Distro and DE/WM: Ubuntu 22.04 on WSL2 in Windows 10
- Versions of Dependencies: 29.0.50
- M-x emacs-version: `GNU Emacs 29.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.33, cairo version 1.16.0) of 2022-09-14`

**Additional context**

I haven't tested on my Linux computer but I think it's related to WSL
