I know a guy who works on core web-dev stuff at Google.<p>He tells me that Edge is <i>often</i> <i>very</i> quirky in very subtle ways. He&#x27;s had to spend <i>many</i>, <i>many</i> hours diagnosing, reporting, and working around quirks in Edge. These quirks <i>sometimes</i> get fixed and sometimes do not, but are <i>often</i> not present in Internet Explorer.
