Files `site/doc/{1.0,1.1}/hledger-ui.md` had to be treated specially because
thay had some other elements inside the same `BulletList` that the `toc` lived
inside. Because only the first element of the `BulletList` is compared, these
extra HTML elements were either dropped or replaced with a TOC at compile time.
By switching to the meta-inline `\$toc\$`, they started to persist into the
resulting HTML. The fix was to drop them from the source markdown.
