Horizontal scrollbar when soft wrapping to window frame

[wion]

If you use one of the included themes, and configure the view as recommended for the intended (iA Writer) aesthetic, the text will nevertheless extend past the right side of the stage for a word or two before wrapping. This results in a horizontal scrollbar for a short distance and a resulting stage jumping behaviour as you type and reach the ends of lines.

The scrollbar only goes away if you reduce the font size to a small size, or expand the window full screen; neither results in good usability, contrary to the point of this bundle; you either end up with really small font or really long line lengths. My old, failing eyes do not like either.

I don't know what causes the text extending beyond the stage, especially when you explicitly configure the view to wrap at the window frame, but it seems to be in relation to changing the baseline font size larger than TM defaults, which is a key part of the desired usability in this case. But then why would this scrollbar happen if you are allowed to change font sizes?

I'm guessing this is a bug in TextMate itself.
