Steps to reproduce: - Go to new extensions shortcut reassigning UI (Manage Extension Shortcuts) from bug 1303384 - Select a command to re-assign - Assign "Ctrl + Page Up" Expected result: Error is shown that a built-in command can not be used. Actual result: The tab is switched (that's the action of Ctrl + Page Up/Down, at least on Linux) and the command is seemingly assigned that shortcut without any error message being shown.
