Re: display table face merging?

[Richard Stallman]

    I don't know whether this represents a bug, missing feature, or
    undesirable feature, but it's annoyed me for a long time.

    If you set up a display table with a face on the glyphs, like
    latin1-disp can do, it doesn't get merged with the face from text
    properties.

This is a bug.  I have been trying to study the display code
to figure out the cause, but I have not yet managed to understand
enough.
