delta: 🐛 Windows Terminal Preview 1.4: Hyperlinks not working

So I was trying the Hyperlink support in Windows Terminal Preview 1.4 but it doesn’t seem to work (hyperlinks source is shown instead of actual links.)

Raw output

Other information

If I instead try the “Validation Steps Performed” snippet in https://github.com/microsoft/terminal/pull/7251#issue-466370410, it works as expected:

In case it helps, these are the relevant options in my .gitconfig:

[core]
	pager = delta

[delta]
	hyperlinks = true
	line-numbers = true
	line-numbers-minus-style = "#660000"
	line-numbers-zero-style = "#333333"
	line-numbers-plus-style = "#006600"
	minus-style = "#999999" "#330000"
	plus-style = "#999999" "#003300"
	minus-emph-style = "#cccccc" "#660000"
	plus-emph-style = "#cccccc" "#006600"
	syntax-theme = TwoDark

I also added this to my Microsoft.PowerShell_profile.ps1 (as per as per microsoft/terminal#7251)
