[vscode] PHP Intelephense extension not work (works partially) on docblock tag @see

As IDE I use VSCode, with PHP Intelephense extension installed.

I created a php file that contains https://pasteboard.co/Ldhhq4LDIlIo.png

If I right click on *My* (line 3), the cursor is positioned on the name 
of the class (line 7).

OK!!!

But, if I right click on *abc* (line 4), a popup appears with the error

***No definition has been found...***

Why?
