OK, it looks like under- and overbrace are outliers among the under- and over- macros, as they do seem to reset the style to text-style. I will look into fixing that.

Similarly, the matrix and array environments do seem to reset to text-style as well.

I have made a pull request for v4 that resolves these issues.

The PR I made does set display-style for the under and over braces.

Fixed in v4.0.
