Typescript doesnt work in Vue components (2019.3.3)

I found, that if I change `extends Mappers` to `extends Vue` it started to work, but before 2019.3.3 that worked fine.

I need this extending thing to use `vuex-smart-module`.

I found a page with list of older versions. But 2019.3.2 didnt fix that. What happened? Please help!

Components defined this way are not recognized, see https://youtrack.jetbrains.com/issue/WEB-31721 and linked tickets.

VSCode works fine with that:

So the problem not in my code at least.

Elena, but that worked for me last year, what happened?

No idea, sorry

I'm working on many projects with that construction, every single component uses this construction, hundreds of components, few big projects. And today, after update to 2019.3.3 that broke. Maybe you could ask someone else what may happened? This is very, very strange.

I've just opened one of my projects on my colleague computer and that works.

Verstion 2019.3.1 works fine.

It seems that this functionality was removed after 2019.3.1, in 2020 year. Could you tell please whats is your plan with that thing? I will stay on 2019.3.1 for now...

Proper Vuex support is being worked on, Vuex had never been fully supported before. Improvements can be expected in 2020.1

Thank you! I hope it will be fixed as soon as possible. I would like to use a maximum of my subscription, on not sit on the old version of the software. :)

P.S. It is first time in my memory (I'm using your IDE for years), when Jetbrains removed important functionality saying "it never worked before" (with actually working cases until 2019.3.1). I didnt even know about that issue until today. With huge project base using this construction. Very discouraging and stange situation :(...

P.S.S. Its not really Vuex problem. This construction is fully TS.
