Grails 6.2.3 Redirect issue when redirected to a url created using LinkGenerator.link

[imranmir]

Expected Behavior

If a url is created using grailsLinkGenerator
String url = grailsLinkGenerator.link(controller: 'menu', action: 'home')
and the url (/red/menu/home) is used to redirect like:
redirect(url: url)
404 occurs as the redirect appends the application name again to the url, e.g.,
http://localhost:8080/red/red/menu/home

This looks to be a regression and asit works in Grails 5. Attaching a Grails 5 and Grails 6 application for bug reproduction.

Actual Behaviour

Redirect should not append the application name again.

Steps To Reproduce

Please checkout the following Grails 6.2.3 project: https://github.com/imranmir/redirect-issue
Boot run the application
Hit the following url: http://localhost:8080/red/test/index
This should ideally have redirected to http://localhost:8080/red/menu/home, but instead it tries to redirect to http://localhost:8080/red/red/menu/home

The bug must have been introduced in Grails 6.1.2 and it seems to also be present in Grails 7.0.0 ...
