Rerender fails when rendering an iterable with None elements inside

[ochrons]

Problem

When rendering a list of components again with a different list, where the first list contains some None (ie. empty nodes), there is a panic:

I'm rendering a li with changing number of children

let description: impl Iterator<Item = Option<VNode>>
...
rsx! {
    li { {description} }
}

some of the items in the iterator are None. The generated HTML looks like

<li data-node-hydration="103"><!--node-id104-->Shape <!--#--><!--node-id105--> into <!--#--></li>

if I replace the empty nodes with some valid rsx (empty string), this problem doesn't occur and then the HTML looks like

<li data-node-hydration="118">
<!--node-id119-->Shape <!--#--><!--node-id120--><!--node-id121--> into <!--#--><!--node-id122--><!--node-id123--><!--#-->
</li>

Expected behavior

Shouldn't panic, but render the new list of items correctly.
