Bug 169748 – _parent named browsing context should not be case-sensitive

• Component: DOM
• Status: RESOLVED DUPLICATE

Browsing context name keywords should not be case-sensitive (https://html.spec.whatwg.org/#browsing-context-names).

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

Concluded in https://github.com/whatwg/html/issues/2443#issuecomment-289043039 that case-insensitive is better.
