xul.dll from Mypal 27.9.4 has a resource entry without any data.
Windows returns this as null-terminated string, instead of pointing past the data.
The first commit adds a test,
the second commit fixes the bugs (and removes the todo_wine).
Original ticket for reference: https://jira.reactos.org/browse/CORE-15781
