I observe some strange behavior of Windows Explorer in folders having in path symlinks to a mapped network drive. Here's an example.
I have a network drive mapped to G: and a symlink testing pointing to a folder on that network drive:

Here's the "New" context submenu that I have right after following the symlink:

Looks ok. And here's the same submenu in the mocking subfolder:

The options list is much shorter. For comparison, the same submenu in the same forlder reached directly:

The "New" context submenu is cut off in the mocking folder when it's reached via symlink but it's ok in the same folder reached directly.
What's the cause? And how can I have the submenu not reduced after following a symlink?
