Expand All keyboard shortcut is missing unless you add a node to the tree

Tested versions

• Reproducible in 4.2.2 and 3.5.3 (seems old)

System information

Windows 10

Issue description

If you open a project and go directly to Editor Settings > Shortcuts and search for Expand All, it is missing from the list.

If you close that window, and then add a node to the try, or otherwise click on a node in the tree, it will add the shortcut to the list (so now if you search the editor settings>shortcut list, Expand All will suddenly be there)

It seems that commands for the shortcut list don't populate until they're first made to appear in editor?

Steps to reproduce

• Open a project

• Go directly to Editor > Editor Settings > Shortcuts and search for the word Expand (before clicking on any nodes)

• Note the lack of an Expand All option

• Close settings, and click on a node/add a node and click on it

• Go directly to the settings/shortcut again and search Expand

• Note the appearance of Expand All

Minimal reproduction project (MRP)

N/A - from my testing it is reproducible in any project that you open and go to settings before selecting a node

No source file or test is identified in the report. Reproduce the issue by opening Editor Settings > Shortcuts before selecting a tree node, then trace how the Expand All command is registered and populated; done means Expand All appears immediately without first interacting with the scene tree.
