[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)(Got a cold so that using sick leaves)]

<ol> and <ul> can have <li> and script-supporting elements (<script> and <template>).

https://html.spec.whatwg.org/multipage/grouping-content.html#the-ul-element

<dl> can have <dt>, <dd> and script-supporting elements. Additionally, can have <div> elements to group some <dt> and <dd> elements.
https://html.spec.whatwg.org/multipage/grouping-content.html#the-dl-element

However, our editor does not expect that they can have <script>, <template> nor <div>. For example, HTMLEditRules::ConvertListType() meets sub-list, it tries to convert the sub-list's types but stops handling if it meets <div>.
