get(slider::RangeSlider) unnecessarily (?) returns an array instead of a range

[ForceBru]

I've just attempted to put the result of a RangeSlider into the title of my plot, but it immediately crashed Pluto:

@bind time_frame RangeSlider(1:length(moving_res.range), right=100, show_value=true)

scatter(
	view(moving_res.M, :, time_frame)', view(moving_res.Σ, :, time_frame)',
	marker_z=moving_res.range[time_frame],
	markerstrokewidth=0, markersize=2, markeralpha=.6,
	title="Clusters over time ($time_frame)",
	label="", xlabel="Means", ylabel="Standard deviations",
	c=:deep,
	fmt=:png
)

I expected the title to become something like "Clusters over time (1:100)". However, Pluto crashed with this error:

I looked at the code of the RangeSlider and was very surprised by get(slider::RangeSlider) returning an array, while, given that the UI element is called RangeSlider, I expected to get a range:

/~https://github.com/fonsp/PlutoUI.jl/blob/a107c6aa010dff1ab9574874143007786fa86451/src/RangeSlider.jl#L64

Indeed, "$the_range" is a big string in my case, so I guess there were problems displaying it...

---

Wouldn't it make sense to return a range instead of an array, like get(slider::RangeSlider) = slider.left:step(slider.range):slider.right?

It returns a vector because JavaScript has no range type, but this can be worked around soon.
