[failing test] add test for adding/removing/re-adding modifier with `if`

[fivetanley]

This test currently fails if the modifier is inside an (if) statement, and if the condition changes from true -> false -> true.

It seems like somehow when the 3rd re-render to true happens, the modifier helper gets a clone of the first two positional arguments (the event name and the callback). The modifier helper gets 4 arguments when it should only be getting two. See the screenshot to see that the first two arguments are the same as the last two arguments:

This should work, but on 3.28.12 throws the following error message:

Uncaught (in promise) Error: You can only pass two positional arguments (event name and callback) to the `on` modifier, but you provided 4. Consider using the `fn` helper to provide additional arguments to the `on` callback.
