Rollup Error with generated /*#__PURE__*/ comments

[jhpaige]

Rollup doesn't know what to do when /*#__PURE__*/ comments in this package are before return instead of before the function. For example:

THIS:
/*#__PURE__*/ return function(t){function e(){return t.apply(this,arguments)||this}o(e,t);var s=e.prototype;

returns this error:
../../node_modules/acorn-typescript/lib/index.mjs (1:14760): A comment

"/*#__PURE__*/"

in "../../node_modules/acorn-typescript/lib/index.mjs" contains an annotation that Rollup cannot interpret due to the position of the comment. The comment will be removed to avoid issues.

THEORY -> RETURN BELOW EXAMPLE INSTEAD FOR MINIFIED FILES? Gets rid of the errors when I test it:
return /*#__PURE__*/ function(t){function e(){return t.apply(this,arguments)||this}o(e,t);var s=e.prototype;

Maybe this has to do with microbundle being outdated? Not sure if it's that or if it's problematic code here.
