Research direction

Start with rc-trigger/lib/index.js at getRootDomNode, attachParent, and attachId, then inspect the rc-util raf callbacks shown in the stack trace. Reproduce navigation from a Suspense-mounted page to another Route while an antd slider unmounts. Done means the unmount transition no longer produces this error, with coverage for the reported scenario if the repository has a suitable test entry point.

Written by the indexing model from the issue text.

Description

Actions

We have an antd slider mounted on a Lazy loaded page (with a Suspense parent).
When we click in the menu of our website, this unmount the current lazy loaded page and load an other lazy loaded page. (Using react router component Route)
During this operation, we sometime have an error popping on rc-trigger library.

Is there any way to protect against this ?
