Breaking change

Proposed change

Breaking out #88575

Turns on break and continue for for loops, which allows short-circuiting of loops to improve efficiency of templates and clarity of code.

    {%- if v == 1 -%}
        {%- continue -%}
    {%- elif v == 3 -%}
        {%- break -%}
    {%- endif -%}
    {{ v }}
{%- endfor -%}

To produce the following output:
