Firefox on iOS: Cannot type in editor after changing focus

[JEleniel]

Does this issue occur when all extensions are disabled?: Yes/No

In Firefox on iOS (iPad Pro 12.9 Gen4) I am unable to type in the editor or terminal windows (whichever I last used) after switching focus to another application and then back to Firefox. Clicking (touching) another pane, e.g. if I was in the editor changing to the terminal and back, resolves the issue.

• VS Code Version: GitHub Codespaces
• OS Version: iOS 18

Steps to Reproduce:

1. Open a GitHub Codespace in Firefox on iOS.
2. Open an editor window to a file.
3. Change to another application.
4. Change back to Firefox.
5. No keyboard input works in the editor.
6. Select a different pane (e.g. explorer, terminal).
7. Select the editor.
8. The keyboard works normally.

Additional Context This is not limited to GitHub Codespaces. The default in-place editor on github.com experiences the same issue. The issue occurs both with and without the Magic Keyboard attached. Being on iOS there are no plugins in Firefox. Safe Browsing is FF is set to Strict.
