When pressing Q while holding an item or hovering over it in any inventory the hit animation is triggered. This is not the case in the Java Edition and should be fixed in order to achieve parity between versions.

I don't think this is a bug. Bedrock isn't meant ti directly emulate java, for example, if you eat, your arm moves to your mouth (look in third person), that doesn't happen in Java. The hit animation is meant to look like you're throwing the item out.
