[A11y] When using task module in MS Teams V2 ,Keyboard using Tab focus get trapped when accessing the close button

Hi everyone, when we using task module in MS Teams V2 ,Keyboard Tab focus get trapped when accessing the close button.
we open the dialog with "dialog.url.open" and "dialog.url.submit" function.
And i find that if we change the tabindex vaule from 0 to -1, it would work as expected.

here is the related html code:

<div data-tid="iframe-container" tabindex="0" aria-label="Entering " data-tabster="{&quot;observed&quot;:{&quot;names&quot;:[&quot;iframe-container&quot;]}}" style="width: 100%; height: 100%; border: 0px; flex: 1 1 0%; user-select: none; display: block;">

Current behavior:

focus.trap.mp4
