Stepping backwards doesn't skip animations when it should

[sleepdeprecation]

At present, stepping backwards (using either the left arrow key, or the backwards seek button) when animations are disabled doesn't do anything differently from when animations are enabled.

Contrarily, stepping forwards (using the right arrow key, or forwards seek button) when animations are disabled causes it to jump straight to the next relevant jumping point (usually the end of a playback).

Stepping backwards should probably do the same thing that stepping forwards does, jump between relevant places, not animate events when animations are off.

I actually did this on purpose. I was thinking that when you go backwards you want to review something. When you go forward with animations off you want to jump to the next interesting thing without a detailed playback.

In a storyboard you can always click on a comment to go backwards. In a normal playback you can move the slider to the beginning.

I'd like to hear someone vigorously complain about the way it is now before we change it.

Than the step forward button / keyboard shortcut should probably also animate. They should do the same thing, instead of one being different.

Mostly because if you step backwards too far for your review, you can't step forwards, you go straight to the end. Or, if you want to go over a small number of changes a couple times, you can't do that easily because you just get sent to the end if you try to step forwards.
