Test for Form History Autocomplete Untrusted Events: Bug 511615
<p id="display"></p>
<!-- we presumably can't hide the content for this test. -->

/**
* Indicates the time to wait before checking that the state of the autocomplete
* popup, including whether it is open, has not changed in response to events.
*
* Manual testing on a fast machine revealed that 80ms was still unreliable,
* while 100ms detected a simulated failure reliably. Unfortunately, this means
* that to take into account slower machines we should use a larger value.
*
* Note that if a machine takes more than this time to show the popup, this
* would not cause a failure, conversely the machine would not be able to detect
* whether the test should have failed. In other words, this use of timeouts is
* never expected to cause intermittent failures with test automation.
