--- Comment #4 from V Stuart Foote <vstuart.foote at utsa.edu> ---
We do not use multi-glyph composites for scalable brackets (bug 32362), so a
single glyph is being stretched to fit into the box holding its node. That
coupled with sm nodes placement also not using floating point to canvas (bug
103322) means that at small sizes the node and its glyph(s) will appear
misallined with other nodes of the formula. Believe this is expected.

I can confirm that the underbrace node in sm example "a + b+c " this is a test
" xyz} underbrace {f}" is not well alligned at smaller size--but at the 'Show
all' scaling in sm the node box is the full width of the formula string, and
the underbrace glyph is correctly scaled and centered in the node. 

None the less the formula is well formed when inserted to Writer canvas as OLE
with a diminutive  "size 2 {}"

So, this is WFM; but needs improvement that only bug 32362, and bug 103322
would bring. This is IMHO => NAB
