This is as expected.
- It is necessary to execute
test()to confirm whether the value ofv-ifhas changed. - The execution of
test()does not imply that the elements ofv-ifwill be re-rendered. Only when the value oftest()changes, will it be re-rendered.

When you modified the contents of msg (which is a ref), it will trigger it's subscriber (which includes the render function) to update, so the render will re-run to update view. Thus test() will be re-run to check if should render it's sub-tree.
