Here are two commands which are both invalid:
Both commands have hoverEvent as an option.
The first command has show_item as its action. Although it can be run successfully, it displays Invalid Item! successfully since it is syntactically incorrect.
What I expected to happen for the last command was...:
Since the command is syntactically incorrect, it should display Invalid Entity! instead.
What actually happened for the last command was...:
It rather crashes the game when hovering over the invalid text. It wasn't like this in the older versions, was it?
Here is a video I have attached below. As you can see, when I have hovered over the last invalid text, the video freezes at the near end of the video, meaning that the game has crashed.
