Thanks!

I think, the global scope is still polluted by three variables. In one of our projects we even ran into problems with that. Minification renames one of those variables into v and because a script from another vendor has also such variable in global scope, we ran into an issue.
I have described the problem here: #15489 because the barrier to open an issue is quite high. I would appreciate some feedback on this.

The problem still exists and sometimes collides even with $ jquery. :(

UPDATE: I more and more think, it is completely on the esbuild side of the story, as the adding of the helpers as well as the minification is on esbuild side. I found this issue over at esbuild: evanw/esbuild#3275 and did a comment.
