testcase

STR:

See test case, the page will

0. check the current focused element by looking at `document.activeElement`.
1. focus() the element
2. set visibility: hidden on the element
3. wait for 100ms
4. check the current focused element by looking at `document.activeElement` again.

Expected:

On Chrome on step 4, the focused element is the body

Actual:

On Safari and Firefox, the focused element is still the element.

Note:

1. The inconsistency suggests that there may be a spec issue here.
2. On Chrome sometime a micro task is enough for the focus to moved away, some times it is not.

Any change here should wait on the resolution of https://github.com/w3c/uievents/issues/236

Bug 29241 is the same issue, but with "display: none" rather than "visibility: hidden".
