Feature Request: Distinct initialClass/initialTitle for extension windows

[thesleepingsage]

Problem

All Zen Browser windows share identical initial window properties:

• initialClass: zen
• initialTitle: Zen Browser

The actual descriptive title (e.g., Extension: (Bitwarden Password Manager) - Bitwarden — Personal — Zen Browser) is only set after window creation.

This prevents Wayland compositors like Hyprland from applying window-specific rules (float, size, position) to extension popups, since static rules evaluate against initial properties at creation time.

Expected behavior

Extension windows should have a distinct initialClass or initialTitle that identifies them as extension-related before the title updates. For example:

• initialClass: Extension: or
• initialTitle: Zen Browser Extension or
• Include the extension name in initialTitle from the start

Environment

• Zen Browser version: latest stable
• OS: Linux (CachyOS)
• Compositor: Hyprland 0.52 (Wayland)

Use case

Tiling window manager users commonly want extension windows (password managers, etc.) to float rather than tile. This is trivial when the window has identifiable initial properties, but currently impossible with Zen.
