Previously, the sidebar JavaScript logic for detecting the "active" page relied on URL and assumed it would end with .html. When using clean URLs without this suffix, this logic would fail to correctly highlight the current page in the sidebar.
This change moves the current page identification to server-side rendering by adding a data-current-link attribute to the HTML root element.
Fixes #2962
