--tsconfig-raw='{"compilerOptions": { "target": "ES5" }}' has same effect with --target es5 since 0.15.8

const a = 7

When transforming the code above with --tsconfig-raw='{"compilerOptions": { "target": "ES5" }}', with esbuild 0.15.7 no errors happen, but with esbuild 0.15.8 "Transforming const to the configured target environment" error happened.

esbuild repl 0.15.7
esbuild repl 0.15.8

I've checked the changelog but didn't find a related change. Is this an intended change?
If so, is there any difference between using --tsconfig-raw='{"compilerOptions": { "target": "ES5" }}' of tsconfig and --target es5?

Looks like this behavior change comes from 3e2374c. However, this new behavior feels like the correct behavior to me. The target setting in tsconfig.json is supposed to be respected by esbuild unless it's overridden at the esbuild level. This has been the case for a while: #277. Arguably the previous behavior of esbuild you're describing was a bug that was fixed.

I agree this is a correct behavior. Thank you for the explaination!
