beforeLoad stuck with the params from first load

[MagMar94]

Which project does this relate to?

Router

Describe the bug

The params is correctly used in beforeLoad for the route the first time it is loaded. The second time the route is loaded, but with another parameter, the beforeLoad-function will use the parameter from the first load again.

Your Example Website or App

https://stackblitz.com/edit/github-hayqaewe?file=src%2Froutes%2Flist_%2F%24number.tsx

Steps to Reproduce the Bug or Issue

1. Navigate to "List" in the minimal example
2. Select one of the links that goes through the beforeLoad in src/routes/list_/$number.tsx (item 1, 2, 3 or the first 4).
3. Click "List" in the menu again
4. Select another one of the links that goes through the beforeLoad in src/routes/list_/$number.tsx (1-3). Notice that the number on the page does not match the one you clicked.

Expected behavior

As a user, I expected the beforeLoad to use the param from the route I clicked, but instead the param from a previous click was used.
