4. Delete the value leaving it just style="" (commit with enter)
=> ASSERTION FAILED: end <= styleDeclaration.length()
(WebCore/inspector/InspectorStyleSheet.h:110 void WebCore::InspectorStyleProperty::setRawTextFromStyleDeclaration(const WTF::String&))
Assertion:
void setRawTextFromStyleDeclaration(const String& styleDeclaration)
{
unsigned start = sourceData.range.start;
unsigned end = sourceData.range.end;
ASSERT(start < end);
ASSERT(end <= styleDeclaration.length()); // <-- this one
rawText = styleDeclaration.substring(start, end - start);
