Course Presentation

I am experiencing some differnences between Firefox and other browsers regarding general display of text in Course Presentation. I have created this example to illustrate how a long lists of text can look ok in Chrome and other browsers but deviate in Firefox. https://h5p.org/node/175035

This could cause problems with partial missing text when the whole slide is used/filled with text: https://ndla.no/nb/node/129553?fag=52234

Hi everyone,

Question/quasi-suggestion follows:  

Is there any way to determine, set or alter the tab order of content types placed in a multi-layer capable app (e.g., Course Presentation), to make sure that learners who use screen readers take in the content on a multi-layered slide in a logical or at least, designer-determined order?  At least one content type that I know of (Image Hotspots) does seem to allow customization of the tab order by the designer.

We use Totara (built on Moodle) and are happy that they have H5P. But there is a problem with course presentation and php. I get the message -  [field:group:coursepresentation:presentation]. Is it a problem Totara/Moodle has to solve and how? Or is it a problem in H5P and when can it be solved?
