Indented line wrapping only working with tabs

[abhro]

If a line is indented with tabs, the hanging indents work just fine. But if spaces are used, the line wraps to the start of the line and doesn't maintain the visual indent.

Code for minimal working example:

### A Pluto.jl notebook ###
# v0.20.21

using Markdown
using InteractiveUtils

# ╔═╡ cd637184-e736-11f0-b7dc-15c90f7670a8
	"This is a very long line. I have created this line for the express purpose of being very long and overflowing the viewport. I have also started this line with a tab to show the hanging indent."

# ╔═╡ bf677b4e-e23b-4adb-b756-1abaec186d86
    "This is another very long line. I have also created this line for the express purpose of being very long and overflowing the viewport. But I have started this line with (4) spaces to show the lack of hanging indent."

Good point! This needs to be implemented in the frontend/components/CellInput/awesome_line_wrapping.js CM extension.

Is it this line?
https://github.com/fonsp/Pluto.jl/blob/4357847bba9f7ab9f00a49bf4098386c6d78a617/frontend/components/CellInput/awesome_line_wrapping.js#L8
i.e., add \s to the regex pattern check for all whitespace at the start?
