PageSpeed Insights Warning

Hi, your plugin works fine, but I need any suggestions. After activating the plugin and doing an analysis in PageSpeed Insights I receive this recommendation or warning:

Avoid using old JavaScript in modern browsers.
Polyfills and transforms allow older browsers to use the new JavaScript functions. However, many of these polyfills and transforms are not necessary for newer browsers. For your packed JavaScript, adopt a modern scripting strategy using module / nomodule function detection to reduce the amount of code sent to modern browsers without losing compatibility with older browsers.

and this is pointed out to me:
Object.defineProperty
Object.defineProperties

The tool tells me that if I solve this I could save 0.15 seconds.
On my part, is there something I can do or is it something that could be resolved in a future update of the plugin? .. any suggestions are appreciated.
