[BUG] Dark Reader breaks Gotty Terminal Emulation during macOS dark mode

# Bug Report

## Describe the bug

On macOS when the OS theme is dark, then Dark Reader causes https://github.com/yudai/gotty (this is a terminal emulation in a browser window) to display the whole content of the emulated CLI in one row only.
## Steps to reproduce

- turn macos dark mode on
- Install gotty (in a unix terminal). See https://github.com/yudai/gotty
- create a browser terminal with `gotty htop`
- open browser (I tested Google Chrome and Brave) with Dark Reader installed
- open the link provided by gotty (e.g. localhost:8080)

## Expected behavior

Full terminal in browser
## Actual behavior

Broken one liner terminal in browser
## Screenshots

macOS day Theme - no problem:
macOS darkmode + Darkreader extension is enabled (but not necessarily in dark mode):
macOS darkmode but Darkreader extension is disabled (for comparison) - no problem again:
## System Information

- OS: macOS 11.3 (Big Sur)
- Browser: Brave 1.24.86, Chrome 90
- Dark Reader Version: 4.9.33

## Additional context

Pausing Dark Reader does not help, only disabling the extension fixes the terminal!
