Rationale
The y-axis zoom feature adds invisible hit-area rects to the live plot SVG using fill: transparent. QC plot export serializes that same live SVG (BaseQCPlotPanel.getExportSVGStr → LABKEY.vis.SVGConverter) and POSTs it to visualization-exportPDF/exportImage, where DocumentConversionServiceImpl renders it with Batik/FOP. transparent is not a valid SVG 1.1 value, so Batik falls back to the initial value — black — and the overlays paint solid black bars over the y-axis labels and the legend.
