previously this test didn't bother checking that it was actually doing anything! d3.selectAll('.parcoords-lines') was an empty set - this must have been refactored at some point - so the .each block never ran. Updated it to not only ensure that it's doing something (expect(canvases.size()).toBe(3, msg); up above) but also to test that something changed (_assertVisibleData(true, 'initial') before the change, _assertVisibleData(false, 'no panels') afterward).

@archmoj before your patch this fails with:

Expected false to be true, 'after relayout - gl-canvas gl-canvas-context'.
