Reloading contest page does not reload button state

[eldering]

Description of the problem

https://onlinejudge.icpc.global/jury/contests/3

Your environment

DOMjudge wfluxor-online branch, but pretty sure it's the same on current main.

Steps to reproduce

1. Open https://onlinejudge.icpc.global/jury/contests/3 or a similar contest URL.
2. Open in a separate window https://onlinejudge.icpc.global/jury/contests/3/edit
3. On the edit page, change the Enable public scoreboard setting.
4. Reload the first window (on Firefox with Linux, I use ctrl+R or F5).

Expected behaviour

I expect to see the changed state of the Enable public scoreboard setting reflected on the first page, but I don't. Only when I go to the URL bar and press enter there, I do see the change. The same is true for the contests overview page.

This is very confusing.

Huh this is weird. How does a refresh not update this…. I will investigate

I can't seem to reproduce this locally...

I noticed similar behavior on other pages. Apparently, some browsers (including my Firefox instance) restore form state on a page reload or back-/forward navigation.
