    html/template: use the same escaper across multiple template executions · a005a8d1
    Samuel Tan authored
    The escaper contains information about which templates have already been
    visited and escaped. This information is necessary to prevent templates
    that have already been escaped from being over-escaped. However, since we
    currently create a new escaper each time we execute a template, this
    information does not persist across multiple template executions.
    
    Fix this by saving an escaper in each template name space which is shared by
    all templates in that name space.
    
    While there, fix error message formatting for an escaping unit test.
    
    Fixes #20842
