Bug: Problem picking suggested @username

If I want to post a toot to @IceCubesApp, when I type just the "@i" part, the app suggests @IceCubesApp. But as you can see in the attached photo, something sometimes puts a space after the I, and when I tap on the suggested username, Ice Cubes doesn't delete everything back to the @ sign and replace it, It just completes typing, so what I end up with is two words: "@I" and "[email protected]"

My keyboard is in English, so the word "I" should always be capitalized--maybe iOS is putting in the space automatically.

Whatever causes the problem, to fix it I think that when the user taps on a suggested @username, Ice Cubes needs to be careful to look back to find the @ sign and replace the whole thing.
