[Problem/Bug]: window.gc collides with page defined consts causing exceptions. #5387
Description
What happened?
#4378 was closed but I would like to request instead of removal a way to rename this method.
Even if this is necessary for internal WebView2 code, it would be very useful to be able to alias it to something that doesn't collide with minified code (eg: window.chrome.gc or window.__webView2Gc etc). The exception caused often stops the whole website working.
On minified pages that use:
const gc = {}
This will cause a fatal exception, additionally it's not possible to run delete window.gc in content scripts ahead of the script either as the property can't be modified.
Importance
Important. My app's user experience is significantly compromised.
