Text out of textbox bug

If i type-d server ip wrongly and tried to fix it, then "text goes out of textbox".
NB!Tried only with space!

Edit: I used copy-paste!

What I expected to happen was...:
I remove first letter(space) and nothing more

What actually happened was...:
I remove first letter(space) and "text goes out of textbox".

Steps to Reproduce:
1. Click "Multiplayer" and "Add Server"
2. Enter server ip with space at start (" 123.123.123.123" instead of "123.123.123.123")
3. Click "Done"
4. Select server and click "Edit"
5. Remove first letter (space)
