When I try to restart a build that has been run as the result of a promotion, drone seems to trigger a new promotion build, but with the variable set to empty - for example, if I run
drone build promote my/repository 123 production
It works fine, but when I hit the restart button in the UI for this build, it does something roughly the equivalent of
drone build promote my/repository 123
(after the 123 intentionally left blank)
Does anyone know if this intentional behaviour?
