Description
"Find All References" only works on modules but stopped working on members from the "Code Explorer" (it works fine on RD 2.5.2.5871 and stops working on 2.5.2.5878). The feature works fine when called from the "Code Pane" context menu.

To Reproduce
SQLiteDB.xls
Steps to reproduce the behavior:

1. Go to 'Code Explorer'
2. DoubleClick on 'SQLiteDB.Introspection.SQLiteSQLEngineInfo.CompileOptions'
3. RightClick on "CompileOptions" in Code Explorer, Find->Find All References.
4. Nothing happens
   If the same feature is called from the Code Pane context menu or from the menu bar, two references are found.

Expected behavior
Should find two references.

Screenshots
Should show this:

#5751 is tweaking stuff in this area, I'll sneak a commit for this issue if I can repro in that branch.

EDIT: repro confirmed.
