Summary: Assertion failure in InspectorStyleProperty::setRawTextFromStyleDeclaration. InspectorStyleSheet.h:111: ASSERT(end <= styleDeclaration.length()); InspectorStyleProperty is being created with an invalid range end. The assertion is harmless, as String::substring checks the passed in length. Reproduced Test Case: <html> <style>html{-webkit-text-size-adjust:none}</style> </html>

Added a stylesheet to inspector/css/getAllStyleSheets.html, which did not cause the test to timeout when running with --debug, as I expected. Inspecting the test page in a debug build asserts as expected.
