Problems with lens and yflip

[RibeiroAndre]

Describe the bug
Trying to use lens with yflip is giving me strange results. In one case, the grey line connecting the lens to its box is in the wrong place. In another case, the original plot gets unflipped.

using Plots
plotlyjs()
plot(rand(100),rand(100),yflip=true)
lens!([0,.2], [0,.2], inset = (1, bbox(0.35, 0.0, 0.4, 0.4)), yflip=true)

Hmm -- seems like a Plots.jl issue. I suggest checking with them!
