@corinagum I added a new WebDriver condition named scrollToBottomCompleted. This can be used to help improve our test reliability.

await driver.wait(scrollToBottomCompleted(), timeouts.scrollToBottom);

@tdurnford, do we want to implement the new scrollToBottomCompleted into any of our previous tests?

[tdurnford]

Yea we probably want to update this line to use the new scrollToBottom timeout instead of making the driver sleep for a second.

@tdurnford please either file an issue or submit a PR :D
