bug: ComponentScript rendered even when 'if condition' fails

Describe the bug RenderScriptItems is called everytime even though the ComponentScript is incapsulated in an if condition.

To Reproduce A small, self-container, complete reproduction, uploaded to a Github repo, containing the minimum amount of files required to reproduce the behaviour, along with a list of commands that need to be run. Keep it simple.

templ button(title string, action *templ.ComponentScript) {
    <button>
            if action != nil {
            onclick={ action }
        }
               { title }
    </button>
}

Expected behaviour I expect passing a nil action to not break rendering of the button.

Screenshots N/A

Additional context I suppose ComponentScript needs to be rendered before its used, however it does not accept nil values.

I imagine the solution would be to accept nil ComponentScript but ignore them.
