Scoreboard NBT Masks always fail to match Entity type specific data

The new NBT selection masks on the "/scoreboard player" functions never matches Entity type Specific data. For Example, logically the following command should match all powered Creepers and set their Test score to 1:

/scoreboard players set @e[type=Creeper] Test 1 {powered:1}

However, the command block indicates that the data does not match:

[23:16:56] The dataTag does not match for 83b57768-bbfe-4d8e-a617-38658a4769cc

This happens regardless of whether I am the owner or not. Also tested on "Fuse" and neither of those match regardless of the actual values
