Next/previous paragraph with selectionBehavior "character" keeps character after paragraph boundary

Execute the 'goto paragraph start' command with the cursor on the first character of a paragraph. Expected (from helix and kakoune): The character that was under the cursor is not part of the new selection Actual: The character that was under the cursor is part of the new selection. To make this clearer, here's an example setup where you can see this happening. Setup a text document like this: ``` foo bar ``` move to the end of the document, and use goto previous paragraph twice. expected: the `b` in `bar` is not selected. actual: the `b` in `bar` is selected.
