/**
|
|
* Test for Bug 1268556.
|
|
* This test checks that when focusing on an input type=number, the focus is
|
|
* redirected to the anonymous text control, but the document.activeElement
|
|
* still returns the <input type=number>.
|
|
*
|
|
* Tests for bug 1057858.
|
|
* Checks that adding an element and immediately focusing it triggers exactly
|
|
* one "focus" event and no "blur" events. The same for switching
|
|
* `style.display` from `none` to `block`.
