it's needed for ARIA test suite: https://dvcs.w3.org/hg/pfwg/raw-file/tip/ARIA/1.0/tests/test-files/accessible-name-input/checkbox-label-embedded-combobox.html we should pick up an accessible name from accessible value. For example, <input type="checkbox" id="test" /> <label for="test">Flash the screen <div role="combobox"> <div role="textbox"></div> <div role="listbox"> <div role="option">1</div> <div role="option" aria-selected="true">2</div> <div role="option">3</div> </div> </div> times. </label> input's name should be "Flash the screen 2 times".
