I suspect this is yet another instance of the org-mode fontification issue
discussed in this thread [1]. In short, there is a limitation in the current
regexp-based parsing approach that org-mode uses which causes fontification to
not work properly when formatting delimiters are placed next to one another.
Another example of this issues would be nested bold and italics. The following:
/*bold italic*/
is only fontified as italic, even though it exports correctly as bold and
italic. However this text:
/some *bold* italic text/
is fontified correctly. The difference between the two is that the first example
has the bold and italic delimiters next to one another, while the latter has
some text between the delimiters.
The reason the export works correctly is because the org-export framework uses
the newer org element parser, instead of relying on simple regular expressions.
