If doc is short, reader perspective button looks like it just doesn't work

[kcarnold]

It returns an empty suggestion, probably because that's what the prompt said it should do.

But the UI doesn't handle this well: it just makes the "Click the button" text spin briefly. A console log message is the only clue:

writing-tools/frontend/src/pages/draft/index.tsx

Line 346 in d13431c

console.warn('Received empty suggestion.');

I suppose it should provide some sort of message that the document is too short.
