Thanks for all your help, guys!
And thanks for the quick replies from Wolfram; I understand the issue
has been addressed in the current build
of Mathematica.

Just for fun, to counter the assertion that there is no discrepancy
between the docs and the behavior of Invisible:

Although the name of the function is "Invisible", the word "invisible"
is not otherwise used in the documentation.
The function description is as follows:

"Invisible[expr] displays as *space* that is the same size as the
formatted version of expr."

The descriptive text accompanying the examples is consistent with this
