After upgrading to 1.1.0, I'm very excited that rf strings support both regex style and format string.  In the attached screenshot, behold how correctly varied `correctColoring` is.  However, any dictionary or class inside of the {} in an rf string is not colored correctly.  See how `myDict['foo']` varies between `incorrectDictionary` and `regularFString`.  The square brackets should be purple, and 'foo' orange, but instead it is all absorbed into red.","author":{"url":"https://github.com/brownjoel","@type":"Person","name":"brownjoel"},"datePublished":"2023-02-27T12:51:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/256/MagicPython/issues/256"}
