Focus text input box after auto-loading captcha

[Shakes4cc]

[Using version 2.13.0]
When the "Auto-load captcha" setting is enabled, the text input box (the one with "Comment" as default text) will become unfocused after opening the quick reply panel, right after the captcha has been loaded.
This seems to be much more likely to happen on slower computers, it happens almost every time on my notebook PC and almost never on my desktop PC, both with the exact same settings.

Please have the script focus the text input box again after loading the captcha.

The captcha focusing on the slider after loading is from 4chan's build in CSS, not from XT.
