This is particularly because of situations like the missing - at the front of a text, where it may be easy to miss that it's missing.","author":{"url":"https://github.com/story645","@type":"Person","name":"story645"},"datePublished":"2023-10-31T04:46:43.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":17},"url":"https://github.com/27232/matplotlib/issues/27232"}
