Yes, that function inserts a static composition that uses
this magic (excerpt from the docstring of compose-region):
------------------------------------------------------------
If it is a string, the elements are alternate characters. In
this case, TAB element has a special meaning. If the first
character is TAB, the glyphs are displayed with left padding space
so that no pixel overlaps with the previous column. If the last
character is TAB, the glyphs are displayed with right padding
space so that no pixel overlaps with the following column.
------------------------------------------------------------
And if there's a static composition, the automatic (dynamic)
composition is surpressed.

I agree. I'll commit a proper fix soon.
