Bug in Featured products output - limit does not exclude disabled products

[zemguru]

Tested with latest Master. But the problem seems to be there for ages.
The same, I suppose, can be found in other modules?

To Reproduce:

• Disable one product, e.g. IPhone 6

Go to Featured module, and set limit to 1 (can be any number, less then total "enabled" products added to Featured module),

Remove all products from Featured.

Add at first IPhone 6 (which is disabled) and then any other "enabled" product.
Save.

Go to homepage (or anywhere, where you have added Featured module display):

There will be no products shown, because we have LIMIT 1, but the first product returned is "Disabled", and result array is sliced AFTER limited return.
