classDiagram: return value "std::unique_ptr" does not display

[sebastianbergt]

Describe the bug The return value of makeToy does not display correctly with std:: or likely any other namespace prefix.

To Reproduce Just try to render the example below. If std:: is omitted, it works again.

Expected behavior Display the makeToy line as +makeToy() std::unique_ptr<Toy>

Screenshots Wrong display:

Code Sample

classDiagram
    class ToyFactory {
        <<factory>>
        +makeToy() std::unique_ptr~Toy~ 
    }
