Past continuous in a subjunctive mood sentence

Question

I was doing some reviewing of the subjunctive mood when I stumbled on this:

In the that-clause, use a past tense form of the verb even if your sentence has a present or future meaning:

I wish he spoke French.

I wish she was coming with me to Paris.

I wish you hadn’t said that.

My question is, why would the second example allow a "was" instead of a "were", being this a subjunctive mood example? Is it because the past continuous requires the auxiliary verb to be conjugated according to the subject?

[*] Sorry if my grammar is not good, it's my first time here and English is not my first language nor my second.

Answer 1

Because people are lazy and speak sloppy English. The second example should indeed be "were". That article is simply wrong.

"I wish" indicates a mood of possibility, not reality, so the subjunctive wereis appropriate, whereas was indicates a definite past happening.
