Problem with content iterations after the user exits the fullscreen mode

Greetings.

I would like to report a bug. We have a problem with content iterations after the user exits the fullscreen mode image slider created via the H5P plugin.

It just happens in Mozilla Firefox.

When the page loads, the user can normally interact with the content on the page, but when the image slider opens in fullscrren mode and exits, the user can no longer click anywhere on the page or scroll the content.

I repeat this only happens in Mozilla Firefox (version 82.0).

The H5P plugin version is 1.15.0

If you need any additional informations or a link from the site, feel free to let me know.

Hi Frzic!

I just had a look at https://h5p.org/image-slider with Firefox V82, but could not reproduce that problem. Is there any error message on the browser's developer console (F12 key) written in red maybe?

Best,
Oliver

Greeting. There is not a single red error message on the browser's developer console.

But I have a few yellow errors:

onmozfullscreenchange is deprecated.

onmozfullscreenerror is deprecated.

mozRequestFullScreen () is deprecated.

Hi Frzic!

Those are just deprecation messages which mean that somewhen in the future, those functions will not be available anymore. Maybe you could share the content that's causing the issues?

Cheers,
Oliver

Hi Oliver.

Thank you for the explanation. You can see the problem on this page:

https://lpc.halpet.eu/courses/osobni-razvoj-asertivnost/lessons/asertivn...

So when you open the slider in fullscreen mode and when you go out, you will no longer be able to click or scroll the page anywhere.

This only happens in Mozilla Firefox.

Hi!

I can reproduce the problem now, but I am not sure what's causing it. I assume BV will have to create a ticket.

Best,
Oliver

I'm glad you reproduced the problem.

Let me know if you still need any information from me.

Hi Everyone,

Ticket has been created, but for some reason I can only reproduce the scroll bar is missing after exiting the full screen. All links and contents works, at least the once that can still be accessed without have to scroll up/down.

-BV

Thanks for creating the ticket.

I noticed another similar problem on the same page. Below the slider is an iframe added through the H5P plugin. The same problem happens. When the user exits fullscrren mode, the page cannot be scrolled nor can the user reopen the iframe.

Thank you for the additional information.

Thank you for your time and patience. Let us know if you need any information or if you have a solution for the problem.

Do we have any update related to this problem?

Hi Frzic,

I wish a have good news but I'm sorry the H5P core team is still in the process of finishing the H5P OER HUB. Any updates will be documented in the ticket I provided in my precious comment.

-BV

Do we have any new information?
