This is in fact intentional, though surprising at first.
pango_layout_set_markup() docs refer to
pango_layout_set_markup_with_accel() which clearly says it "[r]eplaces
the current text and attribute list."  So if you change text later, it's
up to you to clear attribute list.

If pango_layout_set_text() was changed to clear attribute list, that
would break code that first sets attributes on the layout then sets

I'll add a note to the docs for set_text() though.
