[bug] Cannot resize window with custom titlebar when "unstable" feature is enabled on Windows

[Sakamitsu]

Describe the bug

This issue probably reopened this one (#8519), also look at the recent comments for additional context.

Reproduction

1. pnpm create tauri-app
2. Duplicate code from here and update permissions
3. Change tauri.conf.json

"windows": [
      {
        "title": "resize-bug",
        "width": 800,
        "height": 600,
        "decorations": false,
        "transparent": true,
        "shadow": false
      }
    ],

4. Now if you run pnpm tauri dev resize will work.
5. Update Cargo.toml

tauri = { version = "2", features = ["unstable"] }

6. Now resize doesn't work.

Expected behavior

The application is able to be resize when "unstable" feature is enabled and "decorations": false.
