I already checked it and its a thing about replacing

ckeditor5/packages/ckeditor5-engine/src/model/utils/deletecontent.js

Lines 87 to 89 in ea4e36a

	if ( !selRange.start.isTouching( selRange.end ) ) {
	writer.remove( selRange );
	}

 

with:

if ( !startPosition.isTouching( endPosition ) ) {
   writer.remove( writer.createRange( startPosition, endPosition ) );
}

BTW, typing over that selection is affected too.

BTW, typing over that selection is affected too.

Because model.deleteContent() is used there also.
