 #### Fix HTML formatting broken if the beginning tag starts after a list item ([#7181](https://github.com/prettier/prettier/pull/7181) and [#7220](https://github.com/prettier/prettier/pull/7220) by [@sasurau4](https://github.com/sasurau4))
 
 Previously, when Prettier formatted an HTML tag placed just after a list item, it would insert indent and break the relationship of open and close tag. Now, Prettier no longer changes anything.
