These two regressions were missed during a a recent NOTI regeneration.

E.g. noti2611 has

turning into

<ext-link xlink:href="https://top100.diverseeducation.com/HBCUs-2018-2019/?search_degree=Bachelor&amp;search_race=African+American&amp;search_major=Mathematics+And+Statistics&amp;search_school=&amp;search_rank=&amp;search_state=&amp;search=search##anchor">https://top100.diverseeducation.com/HBCUs-2018-2019/?search_degree=Bachelor&amp;search_race=African+American&amp;search_major=Mathematics+And+Statistics&amp;search_school=&amp;search_rank=&amp;search_state=&amp;search=search##anchor</ext-link>

Note how # becomes ## which is invalid. The same thing happens in noti2749.

E.g. noti3096 has
