pm-update-ui-cherrypick

[dnenov]

Purpose

Merging the last changes of the package manager PR has been difficult because of continuous test failures caused by the changes. This PR cherry-picks only the UI-related changes inside this #14655 (which was reverted here #14689)

This PR should not trigger any test issues, as the changes are only on the UI xaml side.

@mjkkirschner I have asked @reddyashish to help with this one, as my account does not let me post jobs it seems. If there is someone I can ask to let me do that, it would help lessen the impact on you guys, and speed up my work I think. Could you maybe tell me who I can approach with this request?
