Router omits current route when navigating by name in shared subroute context

[Luca Stanger]

Reproduction

https://codesandbox.io/p/sandbox/icy-river-y3ppgk?file=%2Fsrc%2Fmain.js%3A14%2C6

Steps to reproduce the bug

1. Open Codesandbox
2. Ensure router is visiting "/random/static1"
3. Click Button "Go to subroute"
4. See router switching to "/random/static2/subroute/1"

Expected behavior

Router stays on route static1 and appends subroute

Actual behavior

Router is switching from static1 to static2 and then appends subroute

Additional information

While creating this issue, I realized that this could be caused due to the fact that the subroute is a "shared" property used by both route static1 and static2. I would expect that I can create new routes and append them to different routes as children, but keep the current active route as active.

router
--/:prop/static1
------------/:prop/static1/subroute/:id (aliased as 'subroute') <--- Switches from this to static2, while only submitting the name 'subroute'
--/:prop/static2
------------/:prop/static2/subroute/:id (aliased as 'subroute')

names are uniques so you need to ensure that your two subroutes use different names instead of just subroute for both of them
