Unexpanded tilde in DIRSTACK[0]

While writing a function to save the directory stack as a script, I
noticed that ${DIRSTACK[0]}, the current directory always has the tilde
unexpanded.

This is the same with bash-4.4.12 and bash-4.3.11.

I was wondering if this is an oversight since DIRSTACK[0] is the same as
PWD, or intentional.

Having the tilde expanded for DIRSTACK[ n >= 1 ] but not 0 is an
inconsistency when the rest of the array is even $'...' quoted when
necessary.
