 layout assert while calculating descendant bounding boxes

$ ./nsgtk -V rlog https://www.piano-tuners.org/history/piano-tuner-history.html

nsgtk: render/layout.c:5131: layout_calculate_descendant_bboxes: Assertion `(box->width != 2147483647) && (box->height != (-2147483647 - 1))' failed.

adding some debug it seems that box->width is UNKNOWN_WIDTH (height is 0)

Its a recursive call in from the "non float" child loop in layout_calculate_descendant_bboxes (lines circa layout.c:5188 ) but its deep in the box stack

 ok its boxes generated from the source data:

 
  • <img class="s-5 l-9 center" src="https://www.piano-tuners.org/site-images/abpt-nav-logo.gif" alt="abpt logo.gif - 2099 Bytes" />


    • remove this and we render it just fine

    in fact just removing the class does. So it is related to the styling

    		 the failing boxes parent is created with render/box_construct.c:1548:box_image()

    called from 863:box_construct_element()

    I cannot immediately see how a child box is created in that case.

    		 The attached test.html and image reproduce the bug here.

    It looks like something related to generated pseudo elements (:after in this case) that is happening on the initial layout pass before image dimensions are known.

    More investigation needed.
