I found that the buttons code makes the Floating TOC script (in ImportJS)'s icons disappear/malfunction:

a.wikia-button:not(.secondary), .wikia-single-button a:not(.secondary), .wikia-menu-button:not(.secondary), input[type="submit"]:not(.wds-button):not(.secondary), input[type="reset"]:not(.secondary), input[type="button"]:not(.secondary), .button:not(.secondary), button:not(.secondary):not(.wds-global-navigation__search-close):not(.wds-global-navigation__search-submit):not(.wds-sign-out__button)

Adding this might fix it:
 * not(.toc-btn):not(#toc-open)
