that is intended change to have two type arguments in StyletroinComponent, it is coming with a new version of styletron(https://github.com/uber/baseweb/pull/5006/files#diff-7ae45ad102eab3b6d7e7896acd08c427a9b25b346470d7bc6507b6481575d519L196-R195)

in @types/styletron-react there was only one type argument for component props, but in the new types now available as part of updated styletron-react package there is also element type - which allows to correctly check types when using $as property

@zxbodya upgrading from 11.1.2 to 11.2.0 fails for TS users, since StyletronComponent has one argument. what should TS user do in order to upgrade?

styled from import { styled } from 'baseui'; returns any because the generic signature is wrong now.

I'm using latest 5.0.3 v of @types/styletron-react.

How to upgrade to baseui 11.2 then? It's using wrong types it seems.

[zxbodya]

baseui 11.2.0, is relying on types published in:

• styletron-react@6.1.0-beta.1
• styletron-standard@3.1.0-beta.1

(@types/styletron-react should not be used, and can be removed after updating styletron)

[simPod]

Shouldn't have been the versions of styletron peer dependencies be raised to 6.1 and 3.1? Cuz it's effectively broken for TS users now.

Though I understand I should update those dependencies before upgrading to 11.2. Hope other users find this too.
