This is happening to me as well. Another thing I've noticed is that the predictive text suggestions will keep the last letter that was deleted.

1. Visit https://quilljs.com/playground on an iOS device
2. Type some text then delete all text or enter a new line
3. Type a letter
4. delete it
5. type another letter
6. the predictive text now has appending letters

Yeah, this is a tough one for usability. I put together a quick and dirty hack. It can be extended to have heuristics around backspacing etc.

q.on('text-change', (d, _, source) => {
  if (source !== 'api') {
    const sel = q.getSelection();
    const [line, ] = q.getLine(sel.index);

    if (!line.children) { return }

    const val = line.children.head.value();
    if (val.length && val[0] === val[0].toLowerCase()) {
      q.updateContents(
        new delta().retain(q.getIndex(line.children.head)).delete(1).insert(val[0].toUpperCase())
        , 'api')
    }
  }
});
