Tests the assertion that "The ‘contentScriptType’ attribute on the ‘svg’ element specifies the default scripting language" by setting it to an unknown value and checking the script is not executed. The test uses an unknown (bogus) script language, which looks exactly like ECMAScript.
Load the test.
The test is passed if string "Good, script didn't run" is displayed. It fails if the string "No! This is not ECMAScript!" is displayed.
