It doesn't.  It might have bugs in its UBA implementation, but
otherwise it just implements the UBA.  I wrote it, so I should know.

I believe in this case there's no bug, since each quote is between an
LTR and an RTL character, so they both take the base paragraph level.

FWIW, I see the same behavior in Notepad.
