The hook SkinBuildSidebar does not allow raw html any more
PHP Fatal error: Uncaught TypeError: Argument 2 passed to SkinVector::getMenuData() must be of the type array, string given, called in /workspace/src/skins/Vector/includes/SkinVector.php on line 292 and defined in /workspace/src/skins/Vector/includes/SkinVector.php:327
I have renamed these tasks to more correct titles to make it clear the error was caused by the extensions since they're returning string where array is required.
The previous title makes it look like this was an error caused not by the extensions themselves.
As I already explained on Gerrit, this returning of HTML string was a legacy behavior that was deprecated and code was left working. It was later (in a different release 1.36, that support for the old behavior was removed), since it's not possible to continue supporting it forever.
