It’s quite difficult to look at the very long footnote here.
It’s difficult to reach to bottom of the footnote. It seems the post in the background moves first. The top of the footnote is hidden behind the header. Since the footnote uses the whole screen, it’s difficult to close the footnote.
It took me awhile to realise what you meant, but yes, that fourth footnote is giant. Once open, it is difficult/impossible to navigate and close cleanly.
And I can move the header too. Though saying that, I can ‘scroll’ the page to the side with any of the inline footnotes open.
