ms-appx: profile icons don't show in taskbar jump list when installed in portable mode #18679
Description
Windows Terminal version
1.22.250204002
Windows build number
10.0.19045.0
Other Software
No response
Steps to reproduce
Install in portable mode, pin to task bar, right-click.
(Note: I copied my settings .json files from an older non-portable install, so the existing profiles used ms-appx URLs.)
Expected Behavior
Jump list should show all profile icons, including built-in ms-appx: ones.
Actual Behavior
Only profile icons that are .exe file paths or https URLs work: ms-appx: URLs or paths/file: URLS for ico/png images do not.
To get profile icons working again, I ended up using https links to e.g. https://raw.githubusercontent.com/microsoft/terminal/refs/heads/main/src/cascadia/CascadiaPackage/ProfileIcons/%7B0caa0dad-35be-5f56-a8ff-afceeeaa6101%7D.scale-200.png in place of the corresponding ms-appx URL. (This is probably not a great idea but it works as a workaround.)
