Malformed .fbx mesh causing extremely large UV Metrics

Asset Importers

-

How to reproduce:
1. Open attached project "MeshMetrics.zip"
2. In Project window, find and select a mesh named "103" a child of "liangyimenposui.FBX" model
3. In Inspector window, observe "Mesh Metrics[0]"

Expected result: the "Mesh Metrics[0]" is small or equal to 1
Actual result: "Mesh Metrics[0]" is equal to 2.6e+07

Reproducible with: 2018.3.6f1, 2019.1.0b3, 2019.2.0a6
Could not test with: 2018.1.9f2 and older, Inspector window had no "Mesh Metrics" value

    Resolution Note:

    The current behaviour is the expected one, large faces with small UV areas require a high mipmap level and this mesh has a good amount of faces with collapsed UVs.
