Well, if I load the plain text file directly into a browser window, it is
usually displayed as <PRE> text (I don't know of any browser which does this
differently), so it would be expected behaviour that the same happens within an
<OBJECT>, at least by default (see below).

The interesting question is rather: Will the HTML document's colors be
inherited? I think this should be defined somewhere (maybe in the CSS of the
surrounding HTML):

  inherit-colors: yes;
  inherit-whitespace: no;

The file referred to by OBJECT would be displayed using the document's body's
colors, but using the default setting for P/PRE, that is <PRE> for a text file.

To set the values that can be inherited by the referenced file, I would suggest
setting the values for <OBJECT>:

  inherit-colors: yes;
  background-color: white;

I think it should not, because the HTML file in the <OBJECT> sits in its own
box, and should not be interfere with what it outside. It can inherit stylesheet
settings from the outer HTML file, however.

IMHO the inner HTML file's style information gains precedence, because the outer
stylesheet may not know about some classes the inner file uses. Thus, the text
will be blue.
