Technologies are markup languages or data formats. If the technology is a markup language, “features” refers to elements and attributes.

The test case is intended to fail because removing the focus from the input field causes a change to the browser window.
The browser must be JavaScript-enabled. The browser window must not be maximized or full-screen. In Opera use overlapping windows (Shift+F5).

“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.
The test case fails the following success criterion at line 8, column 88: http://www.w3.org/TR/2006/WD-WCAG20-20060427/guidelines.html#consistent-behavior-no-extreme-changes-context.
The user initiated the change of context, but did not expect it to be connected to the user's action.
The actual behaviour depends on the user agent. On Windows XP, the following behaviour was observed. In Firefox 2.0 and SeaMonkey 1.1: if the window was maximized, it is resized before it is moved, otherwise it is just moved. In Internet Explorer 6.0, the window is moved, regardless whether it was maximized or not. In Opera 9: nothing happens, regardless whether the browser window was maximized or not. If Internet Explorer 6, Opera 9 and SeaMonkey 1.1 are in full-screen mode (which can be toggled with F11), the window does not move either.
This test case maps to failure F9: Failure of SC 3.2.5 due to changing the context when the user removes focus from a form element (http://www.w3.org/TR/2006/WD-WCAG20-TECHS-20060427/Overview.html#F9).
The test case passes the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20050630/#consistent-behavior-no-extreme-changes-context.
The user initiated the change of context.
The user moved the focus to another form control, which initiated a change of viewport.
