In `list[int]`, both `list` and `int` should be highlighted, whereas only `int` is highlighted currently. The type hint for argument `b` is highlighted correctly (and same for `a`).\r\n\r\n* **Editor name and version**: VS Code 1.51.1\r\n* **Platform**: Ubuntu 16.04\r\n* **Color scheme**: Tomorrow Night (also tested with other ones but none exhibit the desired behavior)\r\n* **MagicPython version**: From the VS Code extension = 1.1.0\r\n* **A screenshot**:\r\n![Screenshot from 2020-11-16 15-29-09](https://user-images.githubusercontent.com/110295/99264994-7a8c9f00-2821-11eb-9277-cc723120d4d8.png)\r\n* **5-10 lines of surrounding code**: None\r\n","author":{"url":"https://github.com/sprt","@type":"Person","name":"sprt"},"datePublished":"2020-11-16T14:43:08.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/229/MagicPython/issues/229"}
