I am using the App Bridge Utility to set modal size. It works perfect, but only on second click of the content, not the first. So the Modal content loads this component. And when I click the thumbnail a second time and re-open the Modal, it looks perfect! But only on a second click. Why is that? The function I am using is: setupModalAutoSizing
The other huge problem with this Polaris component, is if you are scrolled down the screen, looking at resource 49 of 50 say, and you click for the modal, the whole screen shifts right back up to the top, thus losing your place? Why is that? What can I do to prevent a Modal open/close from RE-RENDERING the whole layout?
