esbuild: TypeError: Illegal invocation on --minify-syntax

Hi,

I am using esbuild to bundle the output of a large scala.js program. With --minify-syntax turned on, I see TypeError: Illegal invocation on various places. One on react requestAnimation, another on console.log. It is quite difficult to come up with a minimal reproduce. I am working on one but wonder if you have an idea on what to do.

Thanks
