Full screen issue
When I make the lecture presentation full screen, it adds 3 px height and is not visible. The full screen html code is as follows.
<iframe id="h5p-iframe-33" class="h5p-iframe h5p-initialized" data-content-id="33" style="width: 1920px; height: 3px;" src="about:blank" scrolling="no" title="Title" data-original-w="730" data-original-h="1" frameborder="0"></iframe>
Is there an automatic height setting in this 3px?
