title="NEW - _blank named browsing context should not be case-sensitive"
href="show_bug.cgi?id=169747">https://bugs.webkit.org/show_bug.cgi?id=169747</a> )
Browsing context name keywords should not be case-sensitive (<a href="https://html.spec.whatwg.org/#browsing-context-names">https://html.spec.whatwg.org/#browsing-context-names</a>).
Steps to reproduce issue:
1. `window.open` a document into `_pARent`
Expected behavior:
Browser should choose parent browsing context, if one available, or current browsing context if current is a top-level browsing context.
Actual behavior:
Browser creates a new browsing context (i.e. tab/window)
Browser appears to be choosing a new, not-previously-existing, non-keyword browsing context when given `_pARent`
Subsequent calls to `window.open` into `pARent` are reusing the new browsing context created by the first invocation
