Broken autocomplete

I've had this issue with previous versions of PyCharm. After updating to 2019.2.4 I am having similar issues again.

I tried invaliding the cache and it didn't help at all.

An example of what is happening:

typing: "A." will show suggestions for A based on the objects members.

after typing "B = A" followed by "B." I do not get the right suggestions. Only the suggestions that are based off of previous uses of B show up on the list.

typing "B = A." will show the correct suggestions for A.
