// This test will:

// * Confirm that currently selected button to access tools will not hide due to overflow.
//   In this case, a button which is located on the left of a currently selected will hide.
// * Confirm that a button to access tool will hide when registering a new panel.

// Note that this test is based on the tab ordinal is fixed.
// i.e. After changed by Bug 1226272, this test might fail.
