Wrong story opened under best sorting

Hi, I am learning to implement a router through this example cuz I cannot find a built-in one in sauron. When I open your online demo, it is StorySorting::Top by default. If I switch it to any other sorting and click on the link to open the story or user. It will show the corresponding one in Top sorting in terms of position.

Please let me know if there is a way to fix this. Thank you!

Client crash

Hi, when I build and run this project and then load http://localhost:3000 and click on "best" in the orange top bar of the site and then click on "top" in the same orange top bar, the page stops working. I get output in the console showing that this is due to a crash.

The full output is quite long so I am initially posting only the beginning of the two messages that show up in the console:

client.js:321 panicked at 'must have a parent node, tag: Some("ol"), path: TreePath { node_idx: 110, path: [0, 2, 0, 0, 4] }, for patch: Element(
    Element {
        namespace: None,
        tag: "li",
        attrs: [
            Attribute {
                namespace: None,
                name: "key",
                value: [

                ],
            },
        ],
