Font sizes when typing replies are very small compared to the rest of the page.

For example, this is what I see when I click a post link and reply here:

And here's what I see if I click the "reply" link from the journal instead (note style difference, which puzzles me too but is not the current question):

Would it be possible to make the size of text in the comment textbox be the same as the size of the text in the post? That way, whatever zoom lets me read a post also works when replying.
