In the following example:
@startuml
!pragma svginteractive true
class Car
Driver_1 - Car : drives >
Car *- Wheel : have 4 >
Car -- Person : < owns
@enduml

Due to the underscore in "Driver_1", when hover over Driver_1, the SVG does not shows the link; as compare to Car *- Wheel, and Car -- Person.
May I know how to work around with this situation (underscore in Classname) please?
Cheers,
