Very nice, thank you.

Except the very first page visited in wiki is "doubled" in history - once without the useskin parameter and once with it.

Try to find some wiki page on Google. When you click it, you can't go back to the r###lts, because the previous history entry is the same page, only without the parameter.

@nethew, hi! Yeah, I know about the issue, I tried to fix it, but I think I can't, sorry about that 🤷‍♂️

P.S. You can use Wikipedia search engine to find content.

We could use replaceState() instead of pushState() for the first page visited.
Here are the changes:
Line 25 redirect(href, true);
Line 44 function redirect(inputUrl, replaceHistory) {
Line 68 if (replaceHistory) {
history.replaceState({}, '', newPath);
}
else {
history.pushState({}, '', newPath);
}
Line 85 redirect(url, false);

@nethew, done, pretty nice solution, not gonna lie.

Thank you very much, works well.
