Please provide the steps to reproduce the issue [Bug Report only]

1. Open the stackblitz stackblitz, which does nothing except trigger a change detection every second.
2. Open the Angular devtools on the page.
3. Navigate to the injector tree tab in the Angular devtools.
4. Pan either the environment hierarchy or injector hierarchy diagrams.
5. Observe that the view you panned resets after at most one second, when the change detection happens.

Please provide the expected behavior vs the actual behavior you encountered [Bug Report only]

Actual behaviour: the diagrams move to the roots of the hierarchies whenever change detection happens.

Expected behaviour:

1. If the hierarchy doesn’t change at all, the current state of the diagram (panning and zoom) should stay as they were before the change detection.
2. It would be awesome (though probably hard to achieve) to not change the panning and zoom even if there are (some) changes to the hierarchy, though the exact expected behaviour is probably up to a lot of debate. This part is more of a feature request and probably out of scope for the bug fix, but I wanted to mention it.
