Context Menu Flashes Briefly After Hide (React 18 Batched Updates Issue)

[sotarules]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-contexify@5.0.0 for the project I'm working on.

Here is the diff that solved my problem:

Thanks. @sotarules And I have a question, do we need to change this file react-contexify.cjs.production.min.js to use react-contexify in produciton.

[sotarules]

@supriome no sorry you only have to patch the ESM. I am going to alter that comment to get rid of the CJS patch, that was just me experimenting. I could not figure out which file I had to change.

BTW I'm upset with React development team, specifically React 18 batch updating by default, requiring flushSync to opt out. I've been chasing problems caused by this for weeks now.

@sotarules Thanks, that patch fixed my problem.
