Material UI Select widget label always shrinked

[ValYouW]

The SelectWidget always uses a shrinked label:
https://github.com/rjsf-team/react-jsonschema-form/blob/v5.0.0-beta.16/packages/material-ui/src/SelectWidget/SelectWidget.tsx#L67

The shrink property should be dependent on the current value, whether it is empty or not

I can provide a PR if it make sense.

@ValYouW Yes, any help is encouraged! If you do fix it, please also update the @rjsf/mui package as well since the code is essentially the same. Thanks!

ok. I have forked the repo and trying to build validator-ajv8 I get this error, any idea? I just forked, npm install, and trying to build...
(I built utils/core/mui successfully but can't run the tests without validator-ajv8)

Interesting that you are seeing that when others have not. What version of node are you running. Also, we are removing the ajv8 alias in a pending PR #3371 so hopefully when that merges in the next day or so this issue goes away.

I'm still on node 14 (old projects that I need to support). Weird indeed...

[ValYouW]

Just an update: After running npm install I've noticed that package-lock.json has been updated, so I deleted my node_modules, revert package-lock.json changes and ran npm ci - now it builds successfully.
It seems like a minor change to ajv is breaking it...
