File association does not work

  Windows (appx)

I made a simple program for viewing images and it works as expected.
I'm trying to associate my program with all .jpg files.
My app doesn't show up on the list of programs in the open with context menu when right clicking a .jpg image file.

I have added the file association to the build section of package.json

"build": {
        "fileAssociations": [
            {
                "ext": "jpg"
            }
]}

I extracted the created appx package and looked at the AppxManifest.xml. It doesn't look like any file association has been added like here
(Not sure if this is indicative of anything)

Looks like this was fixed in #4302 and will be released in v22.1.0.
