Well, it did understand the foreground color in the OP's recipe,
didn't it?  it did save the color, but not the bold attribute So then
answer appears to be YES, and there's something Enriched mode should
have done but didn't.

(And there's no reason to "convert to enriched mode", since what
Enriched mode offers is a mechanism to save and restore text
properties.  It's not like it invents some new text attributes or
something, they are just text properties.)
