[Problem] Link to toggle list block does not work

[andrew-polk]

Create a toggle list block.
Copy link to block.
Create a link, paste link to block.
Run conversion.

The link is created with the hash, but the details/summary tag does not have a hash, so the link does nothing.

Example md output:

We have heard a number of reasons why people may not upload their books:

- [I don’t have a Bloom Enterprise subscription.](/why-share-on-blorg#3d8d00b647c048f0878b3b3ab1695d99)


<details>
<summary>“What if we don’t have an Enterprise Subscription?”</summary>

You don’t need a subscription to upload your books to Bloom Library. Anyone can create a free account and upload their books.
