When the previous message is a emoticon, the first capital of your message is ignored

When I send an emoticon and directly after that I start typing a new text message, the first letter is ignored in capitalizing / predicting.

For instance:

me: <emoticon>

Typing: HEllo world, 

Predictions: Ello - Ell... - E...
