Gitlab logo svg not rendered in Inkscape

[Hachmann]

The file https://gitlab.com/gitlab-com/gitlab-artwork/raw/master/logo/logo.svg is displayed correctly in Firefox, but only shows an empty page in Inkscape (0.91 + 0.92 tested).

Only upon ungrouping all the groups, the image shows up.

I assume it has something to do with the masking, whose color is 'unset' (update: set on the mask, but not on the <use> element). Not sure if FF does it right, or if Inkscape does (and what the function of a mask without a color would be... a clip seems to be more suitable).

SVG source was created with:
  Generator: Sketch 3.2.2 (9983) - http://www.bohemiancoding.com/sketch
(same as test case from older duplicate bug #1599723)

Attaching GitLab logo SVG file as currently available to the bug report - external links can can get lost, or the SVG source of the linked file might change.

The fill color of the mask is not 'Unset' - it is 'white', defined by a presentation attribute on the mask definition (the container which holds the <use> reference to the path defining the mask geometry):

                        <mask id="mask-2" sketch:name="path22" fill="white">
                            <use xlink:href="#path-1"></use>
                        </mask>

It works as expected in Inkscape (tested with 0.48.5, 0.91 and lp:inkscape/0.92.x) if the fill presentation attribute is defined for the <use> element (a "clone") inside the mask definition, instead of its parent container (see attached modified version of the test case):

                        <mask id="mask-2" sketch:name="path22">
                            <use xlink:href="#path-1" fill="white"></use>
                        </mask>

Thank you, su_v! (it was 'unset' after ungrouping)

Quoting confirmation from irc (#inkscape-devel):

20:23 Mc : Tavmjong: maybe you can give a quick look at https://bugs.launchpad.net/bugs/1658754 ? (<mask fill="white"><use xlink:href="#path-1" /></mask> gives different result than <mask><use xlink:href="#path-1" fill="white"/></mask> )
20:36 Tavmjong : Mc: I believe that logo.svg is correct. The path referenced by the use element in the mask should inherit the white.
20:37 Tavmjong : Mc: It's kind of messy SVG....
20:37 Mc : but why doesnt the white fill cascade ?
20:42 Tavmjong : Mc: I meant that Firefox (and Chrome) render it correctly... the white does cascade.
