Messages containing just emojis and spaces should still show large emoji

[anoadragon453]

Description

If I enter the message 😀😀, I get large emoji, but if I enter 😀 😀 then I get small emoji. I expect large emoji in both cases.

Solution

Accept space as a valid character in an "emoji-only" message.

Other Considerations

Accept newlines as well.
