This commit fixes a regression from "fix(common): ensure scrollRestoration is writable (#30630)" that caused scrolling to not happen at all in browsers that do not support scroll restoration. The issue was that `supportScrollRestoration` was updated to return `false` if a browser did not have a writable `scrollRestoration`. However, the previous behavior was that the function would return `true` if `window.scrollTo` was defined. Every scrolling function in the `ViewportScroller` used `supportScrollRestoration` and, with the update in bb88c9fa3daac80086efbda951d81c159e3840f4, no scrolling would be performed if a browser did not have writable `scrollRestoration` but _did_ have `window.scrollTo`. Note, that this failure was detected in the saucelabs tests. IE does not support scroll restoration so IE tests were failing. PR Close #38468
