Bugs in content types

I'm experiencing an issue with the 'Image Sequencing' content type where a webpage containing this H5P object unexpectedly jumps down the page to focus on the iFrame.

It only seems to happen on desktops, with all three of my browsers (Chrome, Firefox, Safari).

And it also only seems to happen the first time a page loads. If you scroll back up and refresh, it no longer jumps.

I've tested it with several different Image Sequencing objects, my own and others (inc. H5P).

Our current library version is (1.1.0).

I am facing to a problem .... I can't upload a video.   "A required parameter (contentId) was missing" this is the message from the system

Hi folks,

I try to run an interactive video which is stored in my dropbox (mp4-format) but I get 

the error "unkonwn format". Does anyone know how to fix the problem? I get the same error

when using our server of the university and I thought this was because you need to log in 

before you have access to the video but this seems not to be the only reason why it doesn´t work.

the problem is that we can´t store the video on youtube or vimeo because of rights.
