  Yes, it's a minor issue. I like minor issues :-)

  There are two display problems here:
- a face defined before a heading enters the heading (like the =eee…=)
- a face defined in a heading goes on past the heading (like the *iii…)

  I did some tests with org-emph-re (original value: [1]); the interesting part 
is \\(?:\n.*?\\)\\{0,1\\} because it is the one that allows the face to extend 
up to 1 line below.
  The .*? from there comes from the so-called body in 
org-emphasis-regexp-components, body="."
  I have done some tests and I think that body="\\(?:\\*+[^\n ]\\|[^\n*]\\)." 
fixes the first problem. The expression represents a non-heading line: anything 
not starting by * (except when the initial * precedes a word) and then many 
other characters (a "*?" at the end will be added by org-set-emph-re)
  Final value: [2]

  Is this added complexity worth it? The bug is unpleasant (headings aren't 
coloured as headings) and performance shouldn't be much affected in the common 
case because ^\\* fails early. Only visually it is a complex regexp.

  I don't know how to detect the other problem inside a regular expression. 
Maybe there's some way to ask „don't cross boundaries between headings and
