Test failure: System.Drawing.Drawing2D.Tests.LinearGradientBrushTests.Ctor_PointF_PointF_Color_Color

Note that the failure occurs on Arm64 only!

The test: https://github.com/dmklementiev/corefx/blob/master/src/System.Drawing.Common/tests/Drawing2D/LinearGradientBrushTests.cs has failed with the following details:

Unhandled Exception of Type Xunit.Sdk.EqualException
Message :
Assert.Equal() Failure
Expected: {X=0,Y=0,Width=2,Height=2}
Actual: {X=0,Y=-1,Width=2,Height=2}

Exactly the same problem with another test:
