Library click through to template part focus mode hides sidebar and Navigation editing feature #51839
Description
As part of Navigation on Browse Mode it was agreed that in focus mode for Template Parts it would be useful to display any Navigation Menus present in the blocks within in the browse mode sidebar.
However with the change to Library, when you click on a Template Part you now get taken to the focus mode in "edit" mode (canvas=edit) which hides the sidebar.
Given the value of #51492, we should retain the sidebar. If necessary this can be done conditionally by detecting whether a Navigation block is present in the blocks.
