Dotted line is not shown on a legend item with larger size

[MKoroteev-HORIS]

In the legend customized by override_aes, linetype does not work well for larger values of the size parameter and linewidth has no effect.

ggplot() + \
    geom_rect(aes(xmin=[0], xmax=[1], ymin=[0], ymax=[1], fill=["0"])) + \
    guides(fill=guide_legend(override_aes={'alpha': 0.5, 'size': 10, 'linewidth': 5, 'linetype': 2}))

The border of the legend item is not dotted and the line width is not 5.
