Configuration:
- Web browser and its version: Firefox Nightly 112
- Operating system and its version: Windows 11
- PDF.js version: 3.5.34 [a0ef5a4ae]
- Is a browser extension: N/A

Steps to reproduce the problem:
1. Load https://mozilla.github.io/pdf.js/web/viewer.html
2. Open `issue6931_reduced.pdf` in the demo viewer.

What is the expected behavior? (add screenshot)
That the `<svg>`-element for the filters doesn't take up any space in the viewer.

What went wrong? (add screenshot)
The `<svg>`-element is adding space at the bottom of the viewer, which breaks the scrollbar.
Please see the red marking in the following screen-shot:
