Redirection of pathAlias to aliasTo does not work properly

Link of discussion: https://markmail.org/message/s37whdteejqdzkha

In CMS, we can redirect the user to different path alias using 'aliasTo' field of WebSitePathAlias entity.

Example - 
 <WebSitePathAlias pathAlias="demoHome" webSiteId="CmsSite"  fromDate="2019-05-01 00:00:00.0"  aliasTo="newDemoHome"  />

Based on the above data, if the user hit the 
https://localhost:8443/cmssite/cms/demoHome, the CMS will internally render the content for 'newDemoHome' pathAlias.

As per my observation, the content for  "newDemoHome" is renderd properly (as expected) but the URL of the page (in browser) doesn't change.

We should also update the URL also, i.e. change browser URL from

https://localhost:8443/cmssite/cms/demoHome to https://localhost:8443/cmssite/cms/newDemoHome
