WebKit plugin blocks JavaScript confirm() dialogs — Proxmox noVNC buttons not working

Questions Royal TSX (for macOS)
1

JavaScript confirmation dialogs are suppressed in Royal TSX WebKit plugin.

Proof:

  • Safari: :white_check_mark: confirm() dialog appears (screenshot attached)

  • Remote Desktop Manager (WebKit): :white_check_mark: confirm() dialog appears

  • Royal TSX (WebKit): :cross_mark: dialog is blocked, buttons do nothing

Steps to reproduce:

  1. Create Web Page connection to Proxmox VE (https://ip:8006)

  2. Open VM console (noVNC)

  3. Click “Shutdown” or “Reboot” button

  4. Expected: confirmation dialog appears

  5. Actual: nothing happens

Environment:

  • macOS Sonoma

  • Royal TSX 6.x

  • WebKit plugin

Request: Please fix WebKit to allow JS confirm/alert dialogs, or add option to enable them.
