People picker dropdown gets cut off at Adaptive Card border

I am trying to create a message extension App that would allow our IT Support to create a Jira ticket from selected message. App would work in a Team chat and is written in Python using the BotFramework SDK. After the ticket is created I wish to send an adaptive card as a reply in the chat that would offer some options to interact with the ticket.

Problem is that I want to show a People Picker in my adaptive card. The people picker works, but the problem is that the dropdown is cut off at the border of the adaptive card, so you can barely see it. I've tried different combinations of containers/columns stretch/auto bleed combinations and nothing helps.

I've seen online tutorials where the people picker goes beyond the borders of the Adaptive Card, but they are all 2-3 yrs old and the people picker goes upwards instead of downwards like mine.

I see this issue both in Windows Teams desktop client and web based.

Here is my adaptive card payload:

Interestingly enough, static choices seem to work fine:
