When opening a representation from its URL, it should be automatically visible and selected in the explorer #1070
Description
When opening a representation from its direct URL (by following a shared link, or simply opening it from the onboard area), the representation is open in the main area, but may not be visible in the explorer.
If it was already visible in the explorer, it appears selected, but for example when directly opening a link to a representation in a new browser tab, the explorer is initialized in its default state with only the root elements visible.
This results in a state which is different than when opening the representation by selecting it in the explorer, and does not show contextual information on the element to which the representation is attached.
