Thanks for your first contribution!
It seems your commit removing necessary spaces in comments.
(2 spaces are for line breaks in markdown syntax)

Would you mind checking the diff, please?

[virgilbugnariu]

Yes, looks like my IDE did that automatically, I was not sure if that would be a problem. I will revert the changes on these lines and I'll update the PR. Thanks :)

[yomotsu]

Just merged!
Many thanks!

think this broke using setPosition and setTarget
if I stay before this release it all just works

I do something like this in my code on stored "viewpoints"

Maybe Im using it wrong..

const controllerPromise1 = getCanvasController()
      .getActiveControls()
      .setPosition(
          vp.controllerPosition[0],
          vp.controllerPosition[1],
          vp.controllerPosition[2],
          true
      );

  const controllerPromise2 = getCanvasController()
      .getActiveControls()
      .setTarget(
          vp.controllerTarget[0],
          vp.controllerTarget[1],
          vp.controllerTarget[2],
          true
      );
            ```
