commit 27cf07c629cac8f6d0ab7221f19f747b24582d4f
Author: Andrey Kosyakov <caseq@chromium.org>

DevTools: allow #fragments in DevTools URLs

This keeps fragment identifiers when sanitizing DevTools URL. These are
now used in Audits (LH), which confuses sanity checks when performing
sensitive operations on back-end.
