Fails to show user ID with slash

[shadow-identity]

Steps to reproduce

1. Open a message containing user mention. User ID should have slash "/" in it, for example @s/ash:matrix.org.
2. Tap on user ID

Outcome

What did you expect?

To see the user info, like with any other user.

What happened instead?

It opens https://matrix.to/#/@it/sme:matrix.org. Matrix.to fails to show the user (incorrectly reporting "wrong URL"). So user can not see any user info.

Please note that the slash in the user id @it/sme:matrix.org is not escaped. But even escaped slash URL matrix.to returns the error.

Thanks for reporting.

/ is accepted in the Matrix userId localpart grammar: https://spec.matrix.org/latest/appendices/#user-identifiers, so this will have to be fixed at some point.
