`Camera.preRender` should be public instead of protected?

Description

The official example Mouse Wheel Zoom uses camera.preRender(), but in TypeScript this method is marked as protected, causing type errors.

this.input.on('wheel', (pointer, gameObjects, deltaX, deltaY, deltaZ) => {
  // Get the current world point under pointer.
  const worldPoint = camera.getWorldPoint(pointer.x, pointer.y);
  const newZoom = camera.zoom - camera.zoom * 0.001 * deltaY;
  camera.zoom = Phaser.Math.Clamp(newZoom, 0.25, 2);

  // Update camera matrix, so `getWorldPoint` returns zoom-adjusted coordinates.
  camera.preRender();
  const newWorldPoint = camera.getWorldPoint(pointer.x, pointer.y);
  // Scroll the camera to keep the pointer under the same world point.
  camera.scrollX -= newWorldPoint.x - worldPoint.x;
  camera.scrollY -= newWorldPoint.y - worldPoint.y;
});

Error:

Expected Behavior

Maybe preRender should be accessible as a public method, matching the behavior shown in examples? Or is there other way to fix it rather than @ts-ignore?
