I am using the 0.3.0 version with vite and vite-plugin-stylex. The reason I am using this version is because the plugin throws an error with the latest version. Everything was working fine but I realized borderLeft is not getting recognized. I can see that there is a fix. Is this fix present in 0.3.0 version? Do I have to do anything manually to solve this?

@huseyinsalmansoftdev I understand that there is an issue with 0.4.1 and Vite. You can use borderInlineStart instead of borderLeft as a workaround for now. Fix for 0.4.1 and Vite is coming soon.
