Problems with e.processCSSText on some sites

[HeitorBRaymundo]

Describe the bug
I built a web component that work perfectly in many sites in production mode but for any reason that I cant figure out why in a particular site my web component crashes (screenshots).

The problem is in the bundle file processCSSText function.

Package Manager:
To install Direflow, I used npm

Screenshots

Has anyone ever experienced this?
