Geometry added with LPE : scroll bars not updating unless a zoom is done
Hi,
Thanks for the the new [Tiling Live path effect](https://media.inkscape.org/media/doc/release_notes/1.2/Inkscape_1.2.html#Tiling)
#### Steps to reproduce:
<!-- Describe what you did (step-by-step) so we can reproduce: -->
- open Inkscape
- draw a big object in the page
- Tiling LPE : add rows/columns so that the resulting object will obviously be bigger than the view window
#### What happened?
Scroll bars don't update
#### What should have happened?
After applying Tiling LPE, scroll bar should allow to access the whole document, without having to zoom first.
