Add "true" to truthy values list for windowFeatures
Prior to this CL, window.open(url, '', 'noopener=true') would treat 'noopener=true' as if noopener is false. This is currently per-spec [1] but there is a desire [2][3] to change that. The I2S is here: https://groups.google.com/a/chromium.org/g/blink-dev/c/ePJ4GE6VzVc/m/urs3-4rHDAAJ [1] https://html.spec.whatwg.org/multipage/window-object.html#concept-window-open-features-parse-boolean [2] whatwg/html#7425 [3] whatwg/html#7399 Fixed: 1277613 Change-Id: I5b3a7e985a9bb392c2150846b50369cfcd9b05fa
