How to get context url in JS on Plone >= 4.3.12

The base tag href attribute value no longer (since 4.3.12) points to the context object when in e.g. an edit view. Sadly this breaks JS code that relied on the old behavior. How should the context object url be fetched in JS now? UPDATE: Found an old discussion on this. Apparently this change also broke Plone inline validation (since fixed using a case-specific solution that cannot be used as a global fix).
