 > @ramiy I'm curious how you came across this specific set of tags to add.
 Were they specific ones that you found were needed?

 It was part of Elementor security check. When using `wp_kses_post()` some
 semantic tags removed. So, instead of creating a dedicated solution for
 our needs, we decided to update the `wp_kses_post()` method. But when
 examining this method, I noticed that the allowed HTML tags is not
 complete and I decided to add the additional HTML tags.

 > There are other fundamental tags which aren't allowed yet either, like
 `option` or `optgroup` or `select`, as you can see not even `form` is
 allowed, intentionally: https://github.com/WordPress/wordpress-
 develop/blob/c4186c044f3dd6599f479dcfc5d84ad24bcebea5/src/wp-
 includes/kses.php#L900

 > So it doesn't seem to make sense to add `datalist`.

 No problem, I will update the PR.

 > A tag that is currently missing which would seem to make sense is `wbr`.

 I'll add this tag to the PR.
