Prevent temporary page expansion on block appearance effect (anijs)?

Question

Animation

When a block appears, the effect is an exit on the right, the page expands for the duration of this exit.
On a mobile device, this looks very strange - while the block is moving out, the page is half the screen.
If the block moves to the left, then everything is fine, the page does not expand.
Is there any way to fix this problem so that nothing happens to the page?
