[iOS] Using the keyboard suggestions removes spaces

[koke]

When you use the predictive keyboard on iOS, sometimes there aren't spaces between words

Adding to this:
After a suggestion is inserted and there are no space added, you can try press the space button. This will unexpectedly delete de last letter of the inserted word instead of adding the space.

Edit: Not just space, but any key at all will replace the last inserter letter with the typed one.
