The default size is too small for HiDPI, so set the same height as
the look-in combo box to it. And since in owner draw mode, the height
of combo box is calculated and updated when drawing items, this patch
set button height for toolbar from FILEDLG95_LOOKIN_DrawItem() too.

We test once above that the source does not use the existing allocator, but then
implicitly release the allocator we are testing against (when the source assigns
a new allocator to the sink). As a result, these ok() statements were testing
that newly allocated allocators had a different address than the original
allocator, which of course sometimes fails.

Since we don't need to perform this test more than once anyway, just get rid of
the offending ok() statements.

The tests show that input status is not affected by it.

And fix W11 results.

It corresponds to what NtMapViewOfSectionEx() returns with an
explicitly specified machine.
