Close button overlaps dialog text on incoming verification

(I'm slightly surprised to see this coming in as a dialog rather than a toast or in the timeline?)

I assume this is with somebody who doesn't have cross-signing enabled? We're showing to_devicerequests in a dialog because we don't have a room to show a right panel in. We're still using the old IncomingSasDialog because the new VerificationRequestDialog still breaks the e2e tests and has some UX pitfalls, tracked as #12725

It would be good to work out how we're even reaching this old modal. I haven't seen it myself recently, but there are several link issues above from seemingly both self-verif and other user verif.

This modal is used for to_device SAS verification, such as that incoming from a non-cross-signing device.
