Global sidebar instead of the space sidebar is displayed if a space homepage is set as Confluence site homepage

Summary

When a space homepage is set as Confluence site homepage, the global sidebar will be displayed upon accessing Confluence instead of the space sidebar.
Therefore, space shortcuts will not be displayed upon landing on Confluence unless you go to the actual space or remove the ?mode=global text appended to the URL.

Steps to Reproduce

1. Set a space homepage as your site homepage
2. Access Confluence

Expected Results

The sidebar used is the space sidebar showing the custom shortcuts for users so they can access their documentation easily.

Actual Results

The global sidebar is shown instead and users have to make some extra actions in order to see the space sidebar displayed.

Workaround

Manually remove the ?mode=global appended to the URL in order to have the space sidebar displayed.
