Latest PR to upgrade to MUI5 broke React-Image-Annotate

[seunggyupark]

When I import RIA into my application it runs two css generators resulting in a duplicate deterministic CSS class on elements.

(This is a RIA fork that I made to add custom actions)

see:

mui/material-ui#11628

Unsure if either are related, but my css regressions were fixed by reverting to version 1.0.9, but I was seeing two generated jss classes for each element.
