Rectangle Selector is Top-Left, not Bottom-Left (Comments)

[Wei-LinHsiao]

In scattergl/scatter_plot_rectangle_selector.ts, the comments in the interface state that x and y refer to the bottom left coordinate, when they refer to the top right.

This is solely an issue in the comments; the rectangular selector works fine. This can easily be replicated/ verified by logging the bounding box.

Never mind - I am wrong.
