User can no longer go to the dashboard from anywhere in Confluence site by choosing the site logo in Confluence 5.1

Our Confluence 5.x documentation explicitly states the following:

You can go to the dashboard from anywhere in your site by choosing the site logo at the top left of the page.

This functionality breaks in Confluence 5.1 but works fine in Confluence 5.0.x

Sample scenario and version comparison

In Confluence 5.0.x

1. Set "Site Homepage" in General Configuration to a Demonstration Space (ds)
2. Click on the "site logo" and you'll be redirected to Confluence Dashboard
3. Set "Site Homepage" in http://ConfluenceURL/users/viewmysettings.action to a User Profile
4. Click on the "site logo" and you'll be redirected to Confluence Dashboard

In Confluence 5.1

1. Set "Site Homepage" in General Configuration to a Demonstration Space (ds)
2. Click on the "site logo" and you'll be redirected to the Demonstration Space (ds) instead of Confluence Dashboard. This is not the expected result.
3. Set "Site Homepage" in http://ConfluenceURL/users/viewmysettings.action to a User Profile
4. Click on the "site logo" and you'll be redirected to the User Profile instead of Confluence Dashboard. This is not the expected result.

It seems that Confluence redirect user to the last Site Homepage set in http://ConfluenceURL/users/viewmysettings.action or General Configuration. By right, this shouldn't be the case as in Confluence 5.0.x, the site logo always took you back to the Dashboard - even if the user changed the Site Homepage (global level or user level) to something else.

Workaround

Navigate to Confluence Admin >> Custom HTML and add the following to At end of the HEAD:

<script>
AJS.toInit(function(){
    AJS.$('h1#logo').children().attr("href","/dashboard.action");
});
</script>
