class Example {
/**
* This comment gets removed
*/
static foo() { return null; }

/**
* This one doesn't
*/
static bar() { return null; }
}

Run -

> buble example.js --output output.js

output.js

var Example = function Example () {};

Example.foo = function foo () { return null; };

/**
* This one doesn't
*/
Example.bar = function bar () { return null; };

Reproduce the issue with example.js using the shown buble command and inspect output.js. Trace how comments on static class methods are handled during the transformation, then verify that the comment above Example.foo is preserved while the generated output remains valid.
