Have you checked this on later versions?
4.21.5 is our latest 4.x release
5.0.0-rc.100 is our most recent 5.x candidate (expecting to officially release within the next couple weeks)

Not yet. I am using @formio/[email protected] which is the latest version of it. The package uses formiojs@^4.15.1 as its dependency.

I have made an example using latest RC versions of @formio/react and @formio/js. The problem still exists.
