Path values not decoded properly from URL pathname

Current behavior

Consider an app with two screens, Home and Test, and with the following linking options:

{ config: { screens: { Test: { path: 'test/:id' } } } }

In the Home screen there is a button which calls the following code:

navigation.navigate('Test', { id: 'test=' })

This changes the location field of the browser to /test/test%3D and switches to the Test screen. Currently useRoute().params.id correctly returns "test=".

However, doing a refresh in the browser will change the value returned from useRoute().params.id to test%3D.

The problem seems to be that values aren't passed via decodeURIComponent when read from location.pathname, and thus the encoded value %3D shows up instead of the = character.

Expected behavior

I expected useRoute().params.id to return "test=" even after a refresh.

Platform

• Android
• iOS
• Web
• Windows
• MacOS

Packages

• @react-navigation/bottom-tabs
• @react-navigation/drawer
• @react-navigation/material-top-tabs
• @react-navigation/stack
• @react-navigation/native-stack
• react-native-tab-view

Environment

• I've removed the packages that I don't use

Start with the URL pathname parsing used by the linking configuration and reproduce the refresh case in the linked repository. Compare parameters produced by navigation with those restored from the pathname; done means an encoded value such as test%3D yields test= after refresh on web.
