AnimationState has broken summaries. (Maybe just a JetBrains Rider thing). For example: ClearListenerNotifications in AnimationState is missing a "/// </summary>" at the end of its summary: "The 'summary' start tag on line 2 position 67 does not match the end tag of 'member'. Line 4, position 55". Which makes the summary not show up in Rider.
Also Delay... and AlphaAttachmentThreshold, TimeScale etc has issues too with their summaries, and many other. Rider can't get their summary, so when I hover over them I don't get any info.
