There is a mesh in the Emitter.tsx file, which you can use to see the zoom that will have the seen more visuallly. Just change the opacity to 1.
Now change in constants the minimum amount of blocks that the tangle will have. With less minimum bps, the tangle should grow in size horizontally.
Everything else can also be changed in constants.
For example the amount of movement that the camera will have, or the safe space (padding) that the tangle will have.

I have this behaviour when I open page. Do you have the same behaviour?

Now for me issue described above disappear.

Does this initial zoom expected? Emitter is too far from user and zoom doesn't change depends on new blocks comes.

If yes - approve from me.

I would say that indeed this is expected as explained in the call earlier 🙏🏼, the zoom atm covers the worst case scenario where the BPS are very small, we can polish this in a different PR
