Why is hitTest returning duplicate attributes?

I am trying to get the attributes of a graphic using hitTest and I'm getting some unexpected results. See this example. In the console, the first attributes of the first graphic is displayed once the layer loads. There are lots of attributes, and none of them are duplicated, just as expected.

CLE: 2 CO_RVlu: 0.01 CO_Rmvd: 5.06 C_Seq: 95 C_Storage: 6771 Cmn_Name: "Siberian elm" Cn_DieBack: 15 Cn_Missing: 10 Collected: 1349395200000 Condition: "Fair" Crew: "Linden+ Forrest+ Johnny" Crown_Base: 21 Crown_Height: 53 DBH1: 41 DBH2: 0 DBH3: 0 DBH4: 0 DBH5: 0 DBH6: " " Dedication: " " FID: 1 GroundArea: 2596 Height: 74 Ht_DBH_ft: 4.5 Isoprene_E: 2.7 LAI: 3.96 Land_Use: "I" Latitude: 35.610441 Leaf_Area: 10295 Leaf_Bmass: 144 Live_Top: 74 Longitude: -82.441189 Monoterp_E: 13.2 NO2_Rmvd: 39.24 NO2_Rvlu: 0 Native: "NO" Notes: " " O3_Rmvd: 470.97 O3_Rvlu: 0.42 PM2p5_RVlu: 1.99 PM2p5_Rmvd: 47.84 PM10_Rmvd: 343.45 PM10_Rvlu: 3.73 SO2_Rmvd: 27.64 SO2_Rvlu: 0 S_Value: "3,079.00" Sci_Name: "Ulmus pumila" Spp_Code: "ULPU" Status: "P" Street: "YES" Tree_Age: " " Tree_ID: 102 Tree_Site: "S" Vocs_E: 15.9 Width_EW: 40 Width_NS: 75

Then, when you click on a feature, it logs in the console the attributes of that graphic.

C_Storage: 13227 FID: 1147 c_storage: 13227 fid: 1147

This leaves me with 2 questions:

1. Why aren't all of the attributes shown in the results from the hitTest?

2. Why are the attributes shown duplicated? They appear to be the same except attribute names in the second copy are all lowercase.

I see both issues are fixed when I add outFields: "*" to the featureLayer. I'm just wondering what the default functionality is about.

This will be fixed in 4.19 and you can test against our next build today. https://github.com/Esri/feedback-js-api-next
