<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Editor: Allow `name` attribute on the `details` element in KSES.
The `details` element supports the exclusive accordion behavior among multiple `details` elements by setting a common `name` attribute. The ability to set the `name` attribute in the Details block was added in of Gutenberg 20.2. However, when a user without `unfiltered_html` attempts to save the post, the `name` attribute gets erroneously stripped out. This prevents that.
See [https://github.com/WordPress/gutenberg/issues/56969 Details block: Exclusive accordions].
