Describe the issue

Legend for entries in boxplot are displayed as thin lines as opposed to patches

When we have multiple box plots in the same axis, legend shows thin lines as opposed to boxes and it is difficult to tell entries apart. This issue has been documented at this link with a reproducible example.

Proposed fix

I don't have a solution :(
