Able to click on DM's by clicking just under the profile card

I clicked under my profile card. and clicked by mistake. i expected nothing to happen. but instead, the DM that would be there if the profile card was not there opened.

Go to DMs. Put your mouse under profile cards like I did. Make sure there is DM's where your mouse would be. And they are covered by the card where your mouse is. wait for the click mouse icon to show. and click.
