Hi,
your A1 still has same problem - 2 scroller
https://stackblitz.com/edit/mbdlwi-ef72js
A2:
what if you show calendar range for 10h with 15min step, auto width will have height ( dummy example ) 1000px, height of quick info is ( dummy value ) 150px; In this case you will need scroll to top of page to see quick details. For me, expected behaviour is that quick info is presented as editor dialog. At Top, Bottom, Center of viewport
