#### Steps to reproduce: <!-- Describe what you did (step-by-step) so we can reproduce: --> - open Inkscape - open the attached SVG file #### What happened? See first screenshot. The paths with transparent filling have black filling instead #### What should have happened? Should look like the second screenshot, which is how Google Chrome renders it (and it's correct) (I zoomed out for the sake of the screenshot). The outer paths all have fill="rgba(255,255,255,0)" which is white with zero opacity which is transparent. #### Inkscape Version and Operating System: - Inkscape Version: ... 0.91 r13725 - Operating System: ... ubuntu - Operating System version: ... 16.04    <!-- Example file: Attach a sample file (or files) highlighting the issue, if appropriate. --> <!-- **Thank you for filling in a new bug report!** *More details on how to write a good bug report can be found at https://inkscape.org/contribute/report-bugs/.
