Any additional comments?

I know the reason because the testShow component does not have a common parent element. In the source code, vShow sets the display attribute for style. So my code doesn't work, https://github.com/vuejs/core/blob/fc772dbf7398e8ce961025556594b4a7d3f64871/packages/runtime-dom/src/directives/vShow.ts#L27-L35 but I'm curious is there no other way to achieve this functionality? When my child component does not have a common parent element

You can use a custom prop that sets v-show on all elements in the child, or wrap the component in another element in the parent.

@LinusBorg This is not what I expected, I know that wrapping it in a component works normally. But what I expect is that when the component does not have a common parent element, vShow can also function normally
