HTML error with the multi-level list in Classic Editor

[sasiddiqui]

I have recently created a multi-level list which is throwing HTML validation error:

No p element in scope but a p end tag seen.

This error appears when there is some text between the multi-level list as shown here:

As you see that in Item 1 there is a text and then an unordered list. In this case, extra closing p tag is found in HTML but if the text is removed or the list gets removed then there will be no HTML validation error.

Here is an example link I have created with fresh WordPress install with Twenty Nineteen theme and the Classic Editor plugin.

With Gutenberg: ​https://dev-site-validation.pantheonsite.io/2019/05/22/testing-multi-level-list-with-gutenberg/

Without Gutenberg: ​https://dev-site-validation.pantheonsite.io/2019/05/22/testing-multi-level-list-without-gutenberg/

There is no other plugin installed at this time.

@sasiddiqui thanks so much for this report and also including a handy demo! Can you please share a copy of the raw Gutenberg markup and raw Classic Editor markup for this? I want to make sure that I am testing against the same post data that you have. I've structured a post similarly in Classic Editor and Gutenberg using a soft return between list_item_1 with the desired text between the next level list item successfully without extra markup. Maybe I am misunderstanding the reproduction steps. :)

@antpb Here is the copy of what I have tried.

NOTE: If you copy and paste this directly from the Document then it will create the HTML error or you may add the text directly in the editor as well.

Is there any update on it? Does anyone able to produce this issue?

I am also facing this issue. I am testing this with Classic Editor on the latest version of WordPress 5.2.2

Hi @sasiddiqui. Where do you see the HTML validation error? I can't see your screenshots in the ticket description.

Thanks @sasiddiqui. I see the error now. Closing this as it's the same root cause as #27350.
