Rollup merge of #57636 - GuillaumeGomez:fix-sources-sidebar, r=QuietMisdreavus

Fix sources sidebar not showing up

Fixes #57601.

The order of imports made it so that the sidebar creation was called before the sidebar sources were created. Like this, when the sources are loaded, they create the sidebar as expected.
