[Bug]: IIFE that returns optional call results in syntax error

[p51lee]

Bug report

Version (complete output of terser -V or specific git commit)

$ terser -V
terser 5.15.1

Complete CLI command or minify() options used
I turned off the unsafe option.

$ terser input.js -c unsafe=false

terser input

-- ( x => 0 ?. ( ) ) ( ) . x ;

terser output or error

--0?.().x;

Expected result
Input code throws TypeError:

$ node input.js
input.js:1
-- ( x => 0 ?. ( ) ) ( ) . x ;
               ^

TypeError: 0 is not a function
