We simply don't support break-after well. We currently make CSS2 page-break-after an alias of break-after, but in the latest spec, break-after: always should break depending on the element's context. https://drafts.csswg.org/css-break-4/#valdef-break-before-always

Are there any workarounds for this bug?

Works in Chrome.
