Bug Description

The netplay globe icon (🌐) does not appear in the bottom toolbar even when:

• EJS_netplayServer is correctly set to a valid self-hosted Netplay Server URL
• EJS_netplayICEServers is configured with STUN/TURN servers
• window.EJS_emulator.config.netplayUrl returns the correct value (confirmed via console)
• The self-hosted Netplay Server is running and responding correctly (verified via /list endpoint)

Steps to Reproduce

1. Set window.EJS_netplayServer = 'http://127.0.0.1:3001' (or any valid Netplay Server URL)
2. Set window.EJS_netplayICEServers with STUN/TURN servers
3. Load any game (tested with SNES, MAME, multiple cores)
4. Wait for emulator to fully load and press Play button
5. Observe: No globe icon appears in the toolbar

Expected Behavior

A globe icon (🌐) should appear in the bottom toolbar, allowing users to host or join netplay sessions.

Console Verification

```
frames[0].window.EJS_netplayServer
'http://127.0.0.1:3001'

frames[0].window.EJS_emulator.config.netplayUrl
'http://127.0.0.1:3001'
```

Both values are correctly set, confirming the config is being passed to the emulator.

Environment

• EmulatorJS version: 4.2.3 (stable)
• Browser: Chrome (VM environment)
• Self-hosted Netplay Server: EmulatorJS-Netplay (Node.js + Socket.io)
• Tested cores: SNES, MAME (multiple games)

Additional Context

• No console errors related to netplay
• Tested with latest CDN version (causes black screen, separate issue)
• Tested with multiple game cores (same result)
• Netplay Server is functional (returns {} on /list endpoint)
