Is a bequest nullified if the item undergoes manufacturing processes beyond grinding or baking?

Primary text

If a testator bequeathed flax or cotton and then spun it, or bequeathed yarn and wove it into cloth, or bequeathed cloth and cut it, or bequeathed a lump of metal (*naqra*) and struck it (into shape), or bequeathed a sheep and slaughtered it, the bequest is considered revoked. This ruling is held by the Companions of Al-Ra'y (Hanafi scholars) and Al-Shafi'i in the explicit view of his school. The reasoning is that the item has been prepared for use, thus constituting revocation, similar to the previous cases.
