Epic: V4.x Tools to support JS EMS engine and update dependencies

[shunguoy]

The Javascript engine has been moving from the traditional CommonJS engine to the EMS engine for many new features. Several of our engine-dependent libraries (such as Puppeteer) support only EMS in their new versions. Therefore, our tools have to move to the EMS.

Epic Details

Users will be able (1) to use new libraries that require the EMS; (2) to use our improved accessibility tools due to the use of the latest dependent libraries and a better EMS engine.
