Landing page Outline (Page content index) is not rendered well on mobile and desktop

[estux]

Describe the bug
When I open the Landing page Outline (and I have the Recent Pages section open) on mobile the index doesn't appear on screen.
When I open the Landing page Outline (with the Recent Pages section "closed") on mobile the index appears on the bottom of the page but it's cut out in the end and not fully visible.
When I open the Landing page Outline (with or without the Recent Pages section open) on desktop the index appears at the bottom of the page and it's cut out in the end (with less content displayed if Recent Pages section is open).

EDIT (04/01/2025): this happens on the Landing Page of a Collective. This Collective has only the Landing page (actually the longest one compared to the others Collectives I have, with a lot of headings and sub-headings).
I checked for errors in the console and actually the error is there every time I open the Outline (even on pages where the Outline is displayed well).

To Reproduce
Steps to reproduce the behavior:

1. Open the Landing page of a Collective (shared with public link or with login access) on mobile (the landing page should be longer than the default one, with more headings and sub-headings)
2. Click to show the Outline (page content index)
3. The index content is not visible at all (with Recent Pages section left open)

On mobile with Recent Pages section closed:

1. Open the Landing page of a Collective on mobile (the landing page should be longer than the default one, with more headings and sub-headings)
2. Click to close the Recent Pages section
3. Click to show the page content index
4. The index appears on the bottom of the page but it's cut out in the last part (out of the screen).

You can see a similar behaviour opening the page on desktop (larger screen).

Expected behavior
The index should appear fully on screen when I click to show it.
