Comment (by jonsurrell):

 In [changeset:"61754" 61754]:
 {{{
 #!CommitTicketReference repository="" revision="61754"
 HTML API: Preserve `::set_modifiable_text()` TEXTAREA leading newlines.

 HTML specifies that a single newline is ignored at the start of a
 `TEXTAREA`. If `::set_modifiable_text()` is called with a leading newline,
 ensure it is preserved in the resulting HTML.

 Developed in https://github.com/WordPress/wordpress-develop/pull/11062.

 Props jonsurrell, dmsnell.
 See #64609.
