SPA sub page async example broken?

If you click the links quickly, the behavior seems unintended, as it appends multiple elements.

Hello @MicaelJarniac. Thanks for the report!

We used FakeSubPages for the demo in #5000. It's not the "real deal" but it should act the same.

Now it seems like that implementation falls short in the edge case you have provided.

Kindly file a bug report in Issues, thanks!

Thanks @MicaelJarniac. A bug report is not necessary. I have already created a PR: #5011.

Should be fixed in version 2.22.2 ✔️
