I still can't find a test case that could be fixed by
window--sides-inhibit-check.  Your original test case is fixed
because you removed (set-window-parameter nil 'window-side nil).
And the test case in bug#53662 doesn't need this line because
it was fixed by adding (ignore-window-parameters t).

But maybe there are cases where window--sides-inhibit-check
would help, so we could add it as a precaution.
