Fixes Issue 3096 in chromium "[Find in page] responds each IME composition, making "not found" noises or jumping within the page." This issue is caued by the TextField::Edit class which start searching a page with a string retrieved with the GetWindowText() function every time when a user presses a key. A string retrived with the GetWindowText() function contains a composition string, a string being composed by an IME. This string changes too often and users do not like to start searching a page with the string. To fix this issue, this change removes a composition string from a search string to emulate Firefox.
