I knew that blank lines are needed in certain places when mixing HTML markup with Markdown so that the Markdown will actually be processed. For example:
```
<details>
<summary>
Gory details that are *incredibly* shocking
</summary>
Ha, fooled you!
</details>
```
produces:
<details>
<summary>
Gory details that are *incredibly* shocking
</summary>
Ha, fooled you!
</details>
A blank line is needed after the `summary` tag. However, adding that introduces a new problem:
```
<details>
<summary>
Gory details that are *incredibly* shocking
</summary>
Ha, fooled you!
</details>
```
This looks correct here:
<details>
<summary>
Gory details that are *incredibly* shocking
</summary>
Ha, fooled you!
</details>
But in the post preview, the label is centered (image for reference):

Update: it appears that the centering applies to the completed post as well, in some cases. For example, [if `##` markup for `<h2>` tags is used](https://meta.codidact.com/posts/289288/289314#answer-289314).

Using blockquote around the image makes the post less confusing. As it stands, it's difficult to tell the image content from UI elements.
