Ticket 48870 - Correct plugin execution order due to changes in exop
    
    Bug Description:  Due to changes to make exop handling more efficient, an
    issue was introduced where the execution of plugins was re-ordered. This meant
    the precedence rules when two plugins are equal, were not the same.
    
    Fix Description:  Return early when we find the plugin, rather than continuing
    to loop to find the "last match"
