Why don't gridlines show up in MS Teams for adaptive cards table elements?

Gridlines do not show in MS Teams for adaptive card table elements.
I have MS Teams version 1.6.
Although the result looks fine in the adaptive card designer, when I send the JSON (copied from the "Try It Yourself" section of the webpage at https://adaptivecards.io/explorer/Table.html), to an MS Teams channel via a webhook, the gridlines do not display.

Here's how it renders in MS Teams: (the first table should have gridlines but they don't appear, the lower table without gridlines renders correctly)

    STAMER, GREGORY, Vimal Kumar -
    The bug has fixed now. We have tested this on Microsoft Teams Desktop version 24091.214.2846.1452.
