[BUG] [PlotlyJS] Legend not showing when setting PlotTitle attribute

[MrHenning]

Details

When I set the plot_title attribute, the plot-legend does not show anymore.

Expected:

scatter(
	1:.1:2,
	(1:.1:2).^-2,
	label="2",
	color=:Red,
	# plot_title="test",
	legend=true,
)

Observed:

scatter(
	1:.1:2,
	(1:.1:2).^-2,
	label="2",
	color=:Red,
	plot_title="test",
	legend=true,
)

Oddly I've just seen the reverse - setting plot_title causes legend = :none to be ignored. (Workaround: set plot_title in an earlier call to plot!, then set the legend in a subsequent one.) I imagine it's related.
