Avoid blank page on chapter end behaviour

[upright]

How is the avoid blank page tweak meant to work? Im trying to not have blank pages at the end of a chapter.

In the epub's css its 'page-break-after: always'

I have ticked 'Avoid blank page ...' in tweaks. (see below)
hmm, no image for new users? The text when long-press on the style tweaks > pages and margins > page breaks and plank pages > avoid blank pages on chapter start/end is 'DocFragment { page-break-before: auto ! important; }


Should this be 'DocFragment { page-break-before: avoid ! important; }'?
