Environment

>> Windows build number:
Platform ServicePack Version      VersionString
-------- ----------- -------      -------------
 Win32NT             10.0.19041.0 Microsoft Windows NT 10.0.19041.0

Any other software: No

Steps to reproduce

When using "Fira Code Retina" as fonts and typing -- (two continuing hyphens) or +++ (two continuing marks, plus, for example), these marks could not visible every time what I tried. And pls refer to the screenshot below.

Additionally, my Windows Terminal's config is shown as below:

...
    "profiles" : 
    [
        {
            "acrylicOpacity" : 0.5,
            "background" : "#012456",
            "closeOnExit" : true,
            "colorScheme" : "Campbell",
            "commandline" : "powershell.exe",
            "cursorColor" : "#FFFFFF",
            "cursorShape" : "bar",
            "fontFace" : "Fira Code Retina",
            "fontSize" : 10,
            "guid" : "{61c54bbd-c2c6-5271-96e7-009a87ff44bf}",
            "historySize" : 9001,
            "icon" : "ms-appx:///ProfileIcons/{61c54bbd-c2c6-5271-96e7-009a87ff44bf}.png",
            "name" : "Windows PowerShell",
            "padding" : "0, 0, 0, 0",
            "snapOnInput" : true,
            "startingDirectory" : "%USERPROFILE%",
            "useAcrylic" : false
        },
...

Expected behavior

These continuous marks could show successfully.

Actual behavior

I cannot.

This is because they're ligatures, and that looks like this ligature bug.
