Well, the cant is somewhere in the component. If you update the version of material-ui, everything will be OK .
UPD. Taken from the comments:

Update is not an option, this one is used in the project (
Too much will have to be rewritten

Update not to the latest version then. According to the changelog , this bug was fixed in version 1.0.0-beta.22 (in your example, the previous one, so I think there will be no particular problems).
