Typescript type assertion using angle brackets compiled incorrectly [with reproduction]

[arty-name]

🐛 bug report

I tried to use type assertion with angle brackets in my Typescript files, and Parcel compiled that to invalid code, throwing errors at runtime.

🎛 Configuration (.babelrc, package.json, cli command)

There’s no configuration

yarn parcel build fail.ts pass.ts

🤔 Expected Behavior

Parcel should strip type assertion without breaking the code:

(async()=>{const o=await new Promise((o=>setTimeout(o,10)));console.log(o)})();

😯 Current Behavior

Parcel produces the following code:

(async()=>{await new Promise((e=>setTimeout(e,10))),console.log(a)})();

💁 Possible Solution

No idea

🔦 Context

I thought that <Type>x is clearer than x as Type, but I can still use the latter until the bug is fixed.

💻 Code Sample

// fail.ts
(async() => {
 const a = await new Promise(resolve => setTimeout(resolve, 10));
 console.log(<number>a);
})();

// pass.ts
(async() => {
 const a = await new Promise(resolve => setTimeout(resolve, 10));
 console.log(a);
})();

This was already fixed (probably with #7114). It works correctly with the nightly (yarn add parcel@nightly -E)
