Describe the problem

If the "Preferences" dialog is opened soon after Arduino IDE is started, after closing the menu the File > Preferences menu item is disabled.

To reproduce

1. Start Arduino IDE.
2. Watch the Arduino IDE window. As soon as the menu bar appears, select File > Preferences.
3. The "Preferences" dialog may be empty. Wait for it to populate.
4. Click the "CANCEL" button.
5. Open the File menu.

🐛 The File > Preferences menu item is disabled:

Expected behavior

File > Preferences menu item is only disabled if there is a specific reason the preferences dialog should not be accessible to the user (The only reason I can think of is if the dialog is already open, but that should be handled by making the dialog modal).

Additional context

I bisected the introduction of the bug to 7d6a2d5 / #1581 (does not occur when using the build for 6984c52).

---

Similar to #1722 (note they were bisected to the same commit).

---

The fault does not occur if the IDE startup process is allowed to finish completely (as indicated by the disappearance of the busy spinner next to the mouse pointer).

---

The menu item is enabled in new Arduino IDE windows that are opened when the menu item is in the disabled state in the parent window.

---

Even when the menu item is in the disabled state, I can still open the "Preferences" dialog using the keyboard shortcut (Ctrl+,), or "Arduino: Open Preferences" command palette command.

---

I have experienced a similar fault with Tools > WiFi101 / WiFiNINA Firmware Updater, but have not found a way to reproduce it.
