Bug 1840822, part 2: Add an invisible line break at the end of a contenteditable for InsertLineBreak case. r=masayuki,dom-core
The logic behind this patch is similar to that of part 1, only that this covers the case where a user triggers a line break instead of a new paragraph (i.e. by pressing [Shift/cmd]+[Enter]). If the inserted BR element is followed by a block boundary, another BR element is added. Depends on D182339 Differential Revision: https://phabricator.services.mozilla.com/D182485
