/* A quick patch for vue3-calendar-heatmap's tooltip padding, to avoid conflicting with other tippy contents.
At the moment we could only identify the tooltip by its transition property.
https://github.com/razorness/vue3-calendar-heatmap/blob/955626176cb5dc3d3ead8120475c2e5e753cc392/src/components/CalendarHeatmap.vue#L202
This selector should be replaced by a more specific one if the library adds a CSS class.
TODO: Remove this after https://github.com/razorness/vue3-calendar-heatmap/pull/34 is merged and released,
and then all styles could be merged into `.tippy-box` selector.
