My patch in bug 793686 disturbs the column balancing height and reveal an existing bug that <fieldset> with inset box-shadow can have painting artifact on the fieldset frame's continuation when running reftest in snapshot mode.

Steps to reproduce:
1. Apply the patch that adds `fieldset-inset-2.html` reftest.
2. Run `./mach reftest --setpref=reftest.use-draw-snapshot=true layout/reftests/box-shadow/fieldset-inset-2.html`

Expected result:
The <fieldset> continuation in the second column has no artifact.

Actual result:
The <fieldset> continuation in the second column has green artifact.

Note: The rendering is ok when running ordinary reftest via `./mach reftest  layout/reftests/box-shadow/fieldset-inset-2.html`
