Question: After upgrading to Magento 2.3.3 product collections filtering with the is\_saleable attribute no longer appears to work and the following error is seen in templates calling the collection :

What is the correct way to filter product collections for saleable products in Magento 2.3.3?

Answer: 
When I raised similar question with theme devs for Porto theme which was getting error on the line

```
->addAttributeToFilter('is_saleable', 1, 'left')

```

citing 2nd attribute needed to be an array or null

they sent me back a patch simply removing the call to `->addAttributeToFilter('is_saleable', 1, 'left')` and it seems to be working as before and shows only enabled products

go figure ...
can confirm this
it seems is\_saleable is no attribute in 2.3.3 .. 
the question is: what function had this attribute and what action did remove it?
i have udpated to 2.3.3 on all my webshops and can not look if it was inside in 2.3.2 and before
