Does wmr support typescript Decorators?

[lizhuoqi]

500 ./public/components/mycomp.js - Unexpected character '@' (./components/mycomp.js:10:1)

   8 |  * @csspart button - The button
   9 |  */
> 10 | @customElement('my-element')

I try to use lit for customize components in wmr , and I need the typescript experimentalDecorators feature. But I found that sucrase which used in wmr does not support Decorators syntax. Any solution to solve this problem?
