CozyDialogs: unable to measure consistently the height of the title bar via titleRef

[PolariTOON]

#2010 introduced a titleRef prop on CozyDialogs to be able to measure the height of the DialogTitle from outside the component. Unfortunately this does not work consistently in the app coachCO2 where it seems to be measured as 0 when mounting the map, resulting in the map not being perfectly centered. According to https://reactjs.org/docs/hooks-faq.html#how-can-i-measure-a-dom-node , the useEffect hook + titleRef as a parameter combination may not be suitable for this use case. It is not clear if it can be solved on the app side, so we should likely find another way to expose or watch the height.
