Description

Issue with JS compiling on Safari.
Tests on Safari MacBook (v 14.0.1) / Safari iPhone (v. 12.5.5).

Steps to recreate ### Current behavior

Safari has some issues with the compiled Code from Vanilla JS.
When a function call another function inside, safari can't handle the compiled JS code. (most, there is no log in the Safari console).
In contrast to, if the whole code is handled by one function, Safari can handle the compiled code also.
We noticed that there are also issue related XHRrequests with Fromdata.
