Messaging extension cards
When using messaging extension search, we have found that once the adaptive cards show up after clicking on the (hero) preview card; it gets overlapped by the current tab. So for eg., If we try to view the adaptive card for a github PR in the search bar while having a tab window open; the card gets overlapped by the tab. This bug wasn't present before but has now been showing up in the desktop and browser teams client since past few weeks. We are able to reproduce the bug in Github legacy as well our app - Structural.
