14415	<summary> not handled correctly — incorrect DTD?	Wim Leers		"== Steps to reproduce ==

Originally reported at https://www.drupal.org/node/2656566.

1. Disable ACF.
2. Enter source mode and paste
{{{
<details>
	<summary>
		<div>summary</div>
	</summary>
	<div>content</div>
</details>
}}}
3. Exit source mode.
4. Enter source mode again. 

== Expected result ==
Markup is identical to the pasted markup.

== Actual result ==
{{{
<details><summary></summary>

<div>summary</div>

<div>content</div>
</details>
}}}

Note how `<summary>` is empty.

Suspected cause: `<summary>` incorrectly defined in CKEditor's DTD?


== Other details (browser, OS, CKEditor version, installed plugins) ==
Drupal 8 (8.0.3 or 8.1.x). Go to `/node/add/article`, choose the ""Full HTML"" text format (to disable ACF) and then apply the STR above."	Bug	closed	Normal		General	4.5.5	invalid		wim.leers@…
