fix(browser): Don't use chrome variable name (#10874)

resolves #6880

Using `const chrome = ...` or similar breaks certain setups based on
their bundler config. This makes changes to browser code so that we
never declare a variable named `chrome`.

I tried setting up https://eslint.org/docs/latest/rules/id-denylist to
enforce this, but this unfortunately also looks as types declarations
(so `type K = { chrome: ... }` is problematic.
