When comparing window requesting activation (i.e. focus stealing prevention), don't use Workspace::activeClient() as the active client, but instead the most recent should_get_focus client - that may make a difference if a window was just activated, but the matching FocusIn event that'll make it to be activeClient() wasn't yet processes. Visible with apps that show several windows at the same time after startup.
