When loading an inactive tab, all extensions in the URL bar show a yellow warning icon overlay during loading. While this is convenient to indicate if on a fully loaded page a extension is not operational, I feel that it is not really needed when a tab/page is still loading. It adds a little visual unrest. See video below.
Maybe, in case extensions are then still not operational, the display of these warning icons can be postponed until after the page has completely loaded.
