Box select right after zooming selects features in unzoomed box

[EvertEt]

Describe the bug
When doing a box select, zooming and releasing the box select, all features from the box before zooming are selected.

This only happens when releasing the box right after the zoom, if you wait, the correct features will be selected after releasing the box.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://openlayers.org/en/latest/examples/box-selection.html
2. Draw a box (Ctrl+Drag (Command+Drag on Mac))
3. Zoom
4. Release quickly

Expected behavior
Correct features are selected.

I would be happy to investigate further if you could point me to some possible places that can be related to this.

I would think this has to do with the pixel to coordinate transform, which is not updated while the view is in animating or interacting state. A possible fix would be to check the view's getAnimating() and getInteracting() state. If either is set, register a moveend once-listener on the map and then dispatch the boxend event. If not animating or interacting, the boxendevent can be dispatched immediately.
