Another bug, thank you for fixing two.

If you use this box and attach a file. Then input the CAPTCHA and then press the enter key. The image is not attached to the post.

To test:
1.  Go to a board with a CAPTCHA, 
2. Attach an image using this post box, not the floating one. Only this one at the top of the thread (i.e., as shown in the image attached).
3. Enter the CAPTCHA and after you do, press the enter key in the CAPTCHA box (i.e., do not press New Reply button). This will cause the post to be submitted.
4. You will receive an error that you cannot post a blank message or whatever it says

Do the same with the floating post box and it works with no error.
