Select box does not update when scrolling, until mouse is moved

[SbrowneA]

I have a scrollable div which calls the SelectContainerComponent.update() method on the inner dts-select-container when scrolled. The select area updates correctly; however, the select box does not get updated until the mouse is moved.
Is there a particular reason for this (e.g. performance)?

I would like the select box to also update when I scroll just like a mouse move, is there some setting I have missed or a method call that can achieve this?

Thanks.

Hi, @d3lm sure thing!
Here is short video to illustrate what I mean by the "select box not getting updated (when scrolling at the same time as selecting).
And this is the project on StackBlitz
