Making buttons more responsive on BBPress

Hello,

1. The Favorite link and the Unsubscribe link are not next to each other on mobile, this needs to be corrected, please see first screenshot.
2. The Cancel button is running off the right side of the page. Click the Reply button to expose the Cancel button. The Cancel button needs to align just to the right of the Submit button and not run off the page. The second screenshot shows this.

Support access is enabled.

Thanks.
