• Add cmd option --disable-ws / --disable-web-security to disable Chrome's Web Security. Chrome Web Security is now enabled by default, which is the default ChromeDriver setting. (See https://stackoverflow.com/questions/3102819/disable-same-origin-policy-in-chrome for more info about it). This change makes it easier to use the SeleniumBase Virtual Device Farm from SeleniumBase tests (See https://seleniumbase.io/devices/), which already sets the Same-Origin policy.
• Update jQuery version to 3.5.1.
• Update metadata for charts and presentations.
• Ignore leading and trailing whitespace for assert_title(TITLE).
