noticing that the preview isn't showing up in the share menu. can't remember if that's expected or not but guessing it's not because it shows up in the case where there's no attachments present.

seeing the same thing as react-native-share/react-native-share#613 in adb logs - wondering if that's related. not really sure how to fix, but this doesn't seem to actually break the sharing itself, so hopefully not a major blocker for this PR

UPDATE: this is not a regression as this is the previously observed behavior for observations without attachments, so please ignore this comment 😄

Closing in favor of #1099
