Summary Incorrect Length constructor used after blending negative Length
Gabriel Nava Marino
Reported 2021-09-27 18:25:37 PDT
In some scenarios, BuilderConverter::convertToRadiusLength can return a negative Length of LengthType::Fixed. This is later blended with a Length of LengthType::Calculated which results in the incorrect Length constructor being called.
