ShrinkSafe fails on abstract

[minobun]

I have an js file which should shrinked. Shrinksafe gives me an Parse error for this line. It seems that '.abstract' is that what ShrinkSafe? dont like.

Error:

'abstract' is an ecma future reserved word, and should be avoided in code, at the _very_ least in unquoted form, ideally all together.
