Safari 10.0.1 macOS Sierra
When running Codeception command:
$I->waitForElementVisible(['css' => 'input[type=text][id=UserUsername]'], 30);
in an acceptance test in Safari with Selenium 3.0.1 I receive an error. The screenshot taken at failure clearly displays the element in question. The same test/command is successful in both Firefox and Chrome. The error:

When I run the same test/command in Safari/Firefox/Chrome with Selenium 2.53.1 it finds the element with no problems.
Is there a known issue with this type of locator I'm not finding when going through the forums? Anyone have a suggestion for how to make this work?
Update 12-01-16: This now seems to be more of an issue with waitForElementVisible() command than the Locator. If I change the command to $I->waitForElement(['css' => 'input[type=text][id=UserUsername]'], 30); the test successfully moves forward till the next waitForElementVisible() command.
回答1:
People say visibility checks are broken in the release version of Safari 10. You can try Safari Technology Preview, and if your issue is still there, we can conclude it's some other issue, not the broken visibility checks. If your issue is gone, it'll be not exactly your users' experience, but better than nothing anyways. Also you can try implementing your own visibility checks as a workaround using some script on the browser's side (e.g. this function looks good enough).
To run your tests in Safari Technology Preview, add
'safari.options': { technologyPreview: true }
to the capabilities.
