Okay, F-Script Anywhere to the rescue. Apparently this sequence of
events causes the "scrollable" property of the NSTextFieldCell to become
NO (it starts as YES if you create it in IB). Everything else was the
same. I guess I'll file a radar since there's no reason that this should
happen.
Interestingly, a programmatically created NSTextField's cell also seems
to have its scrollable property set to NO by default (and its line-break
mode is "break by word-wrapping" instead of IB's "break by clipping"). I
guess this is normal since these settings probably make the most sense
for a non-editable text field.

I've found what appears to be a bug in NSTextField but I'm not sure
how exactly to classify it or work around it.
You can reproduce it entirely via Interface Builder (though I
originally found it in code).
Steps:
- Open IB3 and create a Cocoa window
- Drag in an editable NSTextField
- In the Inspector, view its Attributes
- Change Layout from "Scrolls" to "Wraps," and then back to "Scrolls"
- Test drive the interface and try typing in more text than the edit
field can contain
You'll find that once the edit field fills up, the insertion point
pins itself to the right edge of the edit field but the text never
scrolls. It appears that your input is being discarded, but it's
actually being invisibly accepted; the only way to see it is to
copy-and-paste it out or to delete the beginning of the string so that
the characters scroll back into view.
What's going on here? This can't be right.
I've only tested in Leopard but I'm thinking about verifying in Tiger
and then filing a Radar.
For the curious, I got similar behavior in my code by calling
[[myTextField cell] setWraps:NO] (on a text field created
programmatically, via [[NSTextField alloc] initWithFrame:]).
