[bug] [Linux / KDE Plasma Wayland] Title bar buttons dead after restore from tray until maximize or resize

### Describe the bug nvironment OS: Linux (Fedora), KDE Plasma, Wayland App: ERP Boilerplate (Tauri 2.x) Feature: Minimize to tray when closing Expected After closing to tray and choosing Show application, native minimize / maximize / close work immediately. Actual Window restores and looks normal, but title-bar buttons do not respond. Workaround: double-click title bar (maximize/restore) or resize the window; then buttons work. Notes Close-to-tray uses hide(), not minimize. Restore path: show() → optional unminimize() → Linux decoration refresh (maximize/unmaximize cycle). See src-tauri/src/core/tray/setup.rs. How to test npm run tauri dev (or your usual run command). Enable Minimize to tray when closing in settings. Close the main window (hides to tray). Tray → Show application. Try minimize / maximize / close on the title bar. Pass: Buttons work without manual resize or double-click. Fail: Buttons dead until maximize/resize; note whether a brief maximize flicker appears and if buttons work after it (helps tune delay, e.g. 150–200 ms). ### Reproduction _No response_ ### Expected behavior _No response_ ### Full `tauri info` output ```text Environment - OS: Fedora 44.0.0 x86_64 (X64) (KDE on wayland) ✔ webkit2gtk-4.1: 2.52.3 ✔ rsvg2: 2.62.2 ✔ rustc: 1.95.0 (59807616e 2026-04-14) ✔ cargo: 1.95.0 (f2d3ce0bd 2026-03-21) ✔ rustup: 1.29.0 (28d1352db 2026-03-05) ✔ Rust toolchain: stable-x86_64-unknown-linux-gnu (default) - node: 22.22.2 - yarn: 1.22.22 - npm: 10.9.7 [-] Packages - tauri 🦀: 2.11.2 - tauri-build 🦀: 2.6.2 - wry 🦀: 0.55.1 - tao 🦀: 0.35.3 - @tauri-apps/api ⱼₛ: 2.11.0 - @tauri-apps/cli ⱼₛ: 2.11.2 [-] Plugins - tauri-plugin-opener 🦀: 2.5.4 - @tauri-apps/plugin-opener ⱼₛ: 2.5.4 [-] App - build-type: bundle - CSP: default-src 'self'; connect-src 'self' ipc: http://ipc.localhost https://ipc.localhost http://localhost:* ws://localhost:*; img-src 'self' asset: https://asset.localhost blob: data:; style-src 'self' 'unsafe-inline'; font-src 'self' data:; script-src 'self' 'unsafe-inline' - frontendDist: ../dist - devUrl: http://localhost:1420/ - framework: React - bundler: Vite ``` ### Stack trace ```text ``` ### Additional context _No response_
