That didn’t work entirely as expected. As it turns out, you need to do it a bit differently to ignore sticky posts in Ajax requests as well. I ended up doing it as a plugin in order to hook into the right actions and filters, like this:

<?php
/*
Plugin Name: BP Ignore Sticky Groups

function bp_ignore_sticky_groups() {
	$bp =  buddypress();

	if( bp_is_active( 'groups' ) && class_exists('BP_Sticky_Groups') ) {

		if( empty( $bp->groups->extend ) )
			$bp->groups->extend = new stdClass();

		if( empty( $bp->groups->extend->bp_sticky_groups ) )
			$bp->groups->extend->bp_sticky_groups = BP_Sticky_Groups::instance();

		function allow_sticky_groups() {
			if (!is_admin() || (defined('DOING_AJAX') && DOING_AJAX)) {
				remove_action( 'bp_groups_get_paged_groups_sql', 'disallow_sticky_groups', 1, 1 );
				add_filter( 'bp_groups_get_paged_groups_sql', array( BP_Sticky_Groups::instance(), 'alter_bp_groups_query' ), 10, 2 );
			}
		}

		function disallow_sticky_groups( $sql = "" ) {
			if (!is_admin() || (defined('DOING_AJAX') && DOING_AJAX)) {
				remove_filter( 'bp_groups_get_paged_groups_sql', array( BP_Sticky_Groups::instance(), 'alter_bp_groups_query' ), 10 );
				add_action( 'bp_groups_get_paged_groups_sql', 'disallow_sticky_groups', 1, 1 );
			}
			return $sql;
		}

		add_action( 'bp_before_groups_loop', 'allow_sticky_groups', 1 );
		add_action( 'bp_after_groups_loop', 'disallow_sticky_groups', 1 );

		add_action( 'bp_groups_get_paged_groups_sql', 'disallow_sticky_groups', 1, 1 );
	}

}

add_action( 'bp_include', 'bp_ignore_sticky_groups' );

Preferrably the Sticky Posts plugin would enable the site admin to choose when and where the sticky posts should be applied, but the above solution does the trick for me right now.

Btw, I work for a company that supports and maintains a multitude of WordPress-sites and this problem occurs in the same manner on all WordPress-installations having this plugin. Due to this we have to write down all UA-codes before updating and then switch over to Firefox after completing the updates for manually re-entering the UA-codes. I can’t imagine this how it is supposed to work.
