[PATCH] Revert "user32/combo: Set listbox popup height correctly and add tests." (resend)

[Alistair Leslie-Hughes]

From: Sebastian Lackner

This partly reverts commit f7f7b89e2e9117811c91269643868c6d063db5e9.
(Tests are left inplace).

Any application that currently uses "Microsoft.Windows.Common-Controls v6" via
a Manifest has the possibility of breaking comboboxes. Using this version of
the control ensures that dropdown for comboboxes, will show multiple items,
regardless of its height in the resource.
