Sorry for the delay... |

No worries. These are sweeping changes, and people can work around it if they really want to today. |

What about moving this line to the beginning of _zoomInternal() and _dollyInternal() with if ( this.dollyToCursor )?
Then wheel zoom/dolly will reset focalOffsets.
eg
protected _dollyInternal = ( delta: number, x: number, y : number ): void => {
if ( this.dollyToCursor ) this._resetFocalOffsets();

I think mouse drag movement does not affect focalOffset. so, can we remove this?

The idea is to call this whenever any input starts. Otherwise, we may interrupt transitions or animations. Is there a better place to put this?

Could we check the focalOffset value first?
If the value is 0, 0, 0, let's just return and do nothing.

Applies and zeroes focal offsets into the control's spherical coordinates so features like zoom-to-cursor (e.g.
setOrbitPointand then interacting with anOrthographicCamera) andsetLookAtwork without interruption. I have not testedsetLookAtas thoroughly, but expanded the fix to it after reading #303.
