fix: prevent update of scroll position when component is hidden (#2322)

Vertical scroll position is updated every time the component is resized,
when the component is hidden its size becomes zero which triggers an
update of the scroll position - however in this case the position
updates to 0,0 due to all sizes equal to 0 while hidden. This causes the
scroll position to be "forgotten" and reset to 0 upon show and then hide
of the component.
The problem could be clearly visible in story
"welllogviewer-demo-classificationlayout--rtc-tabs-layout" where the
component is positioned in a tab container. When switching to a tab2 to
see the component and then to tab3 or tab1 and then back to tab2 the
scroll position is reset.
