linked message with key separated with "."

[hamsterbacke81]

Hi,
I am not sure if this is a bug or I just simply use the wrong syntax... I try to use linked message with @: in my json language file:

# de.json
 "list.tabletitle": "@:editTitle",
"test.123": "test123",
"test": {
  "111": "test111"
}
"editTitle": "testtitle"

in list.tabletitle, with @editTitle I get the expected output testtitle, but with @:test.123 or @:test.111, I got empty string and with @:(test.123) I get the string literal @:(test.123). Did I do something wrong?
