I have used the Image Sequencing Tool in one of our courses, embedded into Blackboard (not integrated, just iframe embedded).
When you navigate to the page, upon page load, the page scrolls down to the Image Sequencing Tool. This is unfortunate, as it is the 4th activity on the page.
None of the other H5P tools seem to do this (as we are using multiple throughout the course). It seems to exist only with the Image Sequencing tool.
