fix(theme-ui): export jsx as createElement#1604

Conversation
When using the new JSX runtime, Babel will fall back to calling `createElement` (name not configurable) from the configured `jsxImportSource` when there is both an explicit `key` prop and object spread props. This causes a crash when using theme-ui since the custom JSX pragma is only exported as `jsx`. Reexport the `jsx` pragma under the name `createElement` to fix this.

Fix for #1603
The new JSX runtime transformation will sometimes use the
createElementnamed export from thejsxImportSource, howevertheme-uidoes not export its pragma under this name, causing crashes. This PR reexports thejsxpragma under the namecreateElementto fix this. For reference,@emotion/reactcurrently does the same thingA minimal reproduction case is rendering any JSX element with both spread props and a
keyprop:(codesandbox)
As far as I can tell, the tests use the classic runtime, so there is no way to write a test for this other than explicitly doing
import { createElement } from 'theme-ui'and creating a node that way; is such a test worth having, since the use ofcreateElementis essentially an implementation detail of the JSX transform?📦 Published PR as canary version:
