Hello,
Looks like, the issue happens in Firefox and its forks. The fullscreen functionality works correctly in our sample:
https://docs.dhtmlx.com/gantt/samples/02_extensions/11_full_screen.html
But it in snippets, it doesn’t work:

I suppose it happens because of iframes.
MDN says that you need to add the allow="fullscreen" property to the iframe:

https://developer.mozilla.org/ru/docs/Web/API/Document/fullscreenEnabled
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#attr-allowfullscreen

I cannot reproduce the issue locally and cannot fix it in the snippets (probably, because the HTML structure for iframes is not supposed to be editable, but it is only my suggestion).

If you send me a local sample where I can reproduce the issue, I will try to fix it.
