I'm trying to get a treeview to just fill available space in the browser window. Meaning the vertical scrollbar on the treeview should be displayed and the vertical scrollbar on the browser window should not. I am using flexbox and it works perfectly in Firefox and Edge, but the TreeView overwrites my footer in Chrome and the entire TreeView is shown. Any help would be appreciated. I don't understand why the difference in functionality between the browsers. I would have expected Chrome and Firefox to behave the same.
