Comment 1 for bug 1657874

Based on tests with archived builds (on OS X 10.7.5):
- not reproduced with Inkscape 0.91 r13725,
- not reproduced with lp:inkscape/0.92.x rev <= 15237,
- reproduced with lp:inkscape/0.92.x rev >= 15238,
- reproduced with Inkscape 0.92.0 r15299,
- reproduced with lp:inkscape/0.92.x rev 15322;
it seems that the reported regression was exposed with the changes in r15238:
