--- Comment #5 from V Stuart Foote <vstuart.foote at utsa.edu> ---
IIUC, this has nothing to do with the CommonSalLayout-refactoring-regression.
The correct font is selected and rendered.

Rather, this is an issue with sm node layout for the element previews. Seems
that the whole node is not being generated on creation--requiring a second, or
third parsing of the element nodes for the preview.

For example--

1. relaucnh of LO
2. open the sm Formula editor
3. select the elements drop list

-- nodes of Unary/Binary Operators are malformed

4. advance DL to Relations and back to Unary/Binary Operators

-- nodes of Unary/Binary Operators are fully formed

5. advance DL to Brackets

-- nodes for the Scalable brackets are malformed
a.) Round Brackets (scalable) -- left is too tall, right extends out of
section, and incorrect spacing to other node elements

b.) Braces Top (scalable), Braces Bottom (scalable) both have incorrect spacing
to other node elements

6. advance DL to Formats and back to Brackets

-- nodes for scalable Braces Top & Braces Bottom now correctly formatted; but
node for Round Brackets (scalable) is not fully correct. I.e. while left and
right are correctly scaled, the position of elements including placement of
right remains wrong for the node preview.

7. advance DL to Formats and back to Brackets

-- node for Round Brackets (scalable) is now fully correct

Believe this multi-pass composition of nodes for the element previews is
burried in the way the sm module handles its node composition, and is not
wrapped up in the font handling.
