"Next Chapter" button not clickable in index chapters

If you look at the video below, the next button in the index chapters isn't clickable, like it is in child chapters.

The problem seems to be the sidebar(nav.pagetoc) taking more height and overlays on top of this button because of the higher z-index. The fix would be probably to change height to max-height instead. LMK what you think.

I'll be happy to create a fix for it.

	.pagetoc {
	position: fixed;
	width: 200px;
	height: calc(100vh - var(--menu-bar-height) - 10rem);
	overflow: auto;
	z-index: 1000;
	}
