Error loading H5P via AJAX persists in D8 version of the module

When using the ajax call to show a node containing some h5p content, the content is rendered correctly after a page reload, but not when the same ajax call is repeated without page reload.

How to test?
1) generate a "H5P test" page that shows some h5p content
2) generate a second "AJAX reference test" page with "full html" text containing an "a" element with a href to the first page. Add the ajax options to "a", so that the referenced page is loaded in a modal window or off canvas or in a named html element on the same page.
3) open the AJAX reference page
4) click on the link, to open the H5P test page in a modal window (off-canvas, whatever) using ajax.
5) repeat this again
6) reload the AJAX reference page and repeat 4 and 5.

Step 4 works OK, step 5 doesn't.

Note

This seems to be an ancient issue that is already reported for v7 version of the module. While some patches were proposed that apparently resolve the issue, this apparently wasn't acceptable because it touched the code that is supposed to be the same across different platforms.

    Hi,

    Facing the same problem.
    Basically, it is easy to reproduce like this with NG lightbox module for example.

    Prerequisites
    1. List H5P content using views
    2. Configure NG lightbox to open H5P content to a modal window (core modal)

    repeat the problem:
    1. Click a H5P link which opens H5P content to a modal = All is working
    2. Close the modal
    3. Click again, any H5P link which opens it to a modal. = H5P content does not load, the other fields of that page is visible.

    I can confirm that this still happens in 2.0.0-alpha5. Here's some sample markup to add to a body field with Full HTML enabled:

    <p>
Click the links below.
</p>
<p>
    <a class="use-ajax" href="/node/16" data-dialog-type="modal">Basic Page</a>
</p>
<p>
    <a class="use-ajax" href="/node/9" data-dialog-type="modal">H5P Page</a>
</p>

    When clicking that first link (the basic page), I see the node content any time I click it. When I click the second (H5P link) I see the H5P the first time I click it. If I close the modal and click the link again, I see the page title and author info, but the H5P doesn't render. Further, when examining the JSON data that is returned from the AJAX callback, the first response includes 'add_css' and 'add_js' commands and the second click AJAX data does not include them. Further playing with this indicates that sometimes this is true for the first click -- no 'add_css' or 'add_js' commands and no rendered h5p, so it's not quite as simple as the first time always works.
