I built my own epub3 book, from multiple xhtml and css files.
Some xhtml files end with a <details>/<summary> construction like this:
......
<details>
<summary>text</summary>
...say, ten more lines of details
</details>
</section>
</body>
</html>
When the xhtml file is loaded, the <details> is closed of course and I have to press the <summary>text</summary> to pull down the remaining lines of the <details>.
But then, only a few (3 or so) lines appear and I have to scroll up or down a **tiny** bit for the rest of the <details> to appear.
It's not that the full <details> are open below the bottom border, but they have not appeared at all yet.
<details> halfway the xhtml file behave normally.
What can I do to remedy this?
