Game Crashes and Bugs on hasitem

newly added hasitem target selector has so many bugs:

• commands such as /me @s[hasutem= {item=potion,data=-1}

  ] directly crashes the game

• can't target concrete powder at all. [hasutem= {item=concretepowder}

  ] doesn't work

• block item's data values aren't supported, which means i can't target green wool, stone solely
• Using [hasutem= {item=potion}

  ] can only target water bottle, instead of targeting all potions.

• It doesn't check items on the cursor, unlike /clear
