On 21F79, both in stock Safari and the latest STP, https://nbss.edu/continuing-education/ Make the viewport width wide. The calendar in the lower part of the page oscillates between two layouts. Does not happen in Chrome.

iframe resizing from JS: case "resize": return e("Got message 'resize', resizing iFrame height to " + o[2] + "px."), this.container.children[0].style.height = o[2] + "px", t();

It seems to be resizing the iframe to `$('body').outerHeight(true) + 48` within the iframe; not sure where 48 comes from, maybe related to default scrollbar size?
